Fix parsing od the first leading codes/charactes in Cisco show bgp
ipv4/6 received/advertised when all four positions are used for codes
line on line:

 *>i 92.43.24.0/21    217.31.48.125            0    512      0 47949
 47949 i

Add timeout parameter to defaults.

Add more explanatory exception message to BIRD timeout handling code
than the previos catch-all else branch with one Exception was.

Add debugging messages to ulg.py around new worker process forking.

Pure styling fixes.

ulg.css obsoleted as Alix created brand new style.css.

Fix javascript catch when setting document.xxx.innerHTML='<something='somethingelse'>'; to escape inner quotes.

Use CSS for whole page formating.
Rework forms (including the autogenerated parts).
Change table color generation mechanism.

Fix IPv6 prefix annotation in show route all ... command in BIRD
command decorator.

Add possibility to set a name of the BIRD router in BirdRouterLocal
object.

BIRD over SSH over pexpect returns first line with two birdc prompt
concatenated to the result (answer). This needs to be removed as well
as the first two lines that contains BIRD login message.

Refactor rescanPeers and rescanRoutingTables.
Replace getPeers and getRoutingTables functions.
Add support for save and load peers list and RT list into persistent
storage.
Add rescanHook function.
Add loadPersistentInfo call into init of BirdRouterRemote.

Add BirdRouterRemote class.
Implement SSH pexpect session handler.
Inherit/copy synchronous rescanPeers rescanRoutingTables from
BirdRouterLocal (slow, TODO: implement async versions).

Issue logout when the command finished and result is written.

Refactor BIRD BGP graph generation by means of finishHook and arbitrary
data in sessions. FinishHook is used to set off result parsing and the
preprocessed list of ASes in paths is saved along with AS names resolved
from whois in the session data. In the display phase it is only
transformed into nodes and passed to graphviz.

Implement arbitrary data into sessions.
Implement finishHook to TextCommand.
Refactor graph generation of Cisco by the abovementoined mechanisms.
Add whois client.
Refactor whois client calls in ulg.py in action whois.
Add simple annotation by AS names in BIRD BGP graph.

ARIN whois server does not allow queries for 1.2.0.0/20 but we can query
any IP address in that block.
Remove the /<netmask> part and it works.

Implement whois CGI action.
Link decorator helper functions to this new action instead of RIPE DB
web interface.
Put link to URLs to RIPE DB web interface frol old defaults.getANSURL()
and defaults.getIPPrefixURL() functions to the header of the new Whois
output in the modal window. Open the links to RIPE DB in new
windows/tabs.

Prepare for BIRD remote router via SSH by refactoring current class
BirdLocalRouter class and pull out common stuff to a new BirdRouter
abstract class.

Add (now empty) BirdRemoteRouter class.

IP address annotation (clickable modal window/href) in the show bgp
ipv4/6 unicas <prefix> output added.

In future it should be linked via decorator_helper to whois client /
DNS resolver to give more meaningful explanation of observed network
topology.

Fix condition when the CiscoCommandShowBgpIPv46Select.decorateResult()
hits the end of the result array/file and the e index falls beyond the
end which causes exception.

Also prepare Cisco for decorators of show bgp ipv4/6 commands.

Bugfix situation when listing slice is cut from text in session result
file it may happen that multi-line result is cut apart on listing
boundary which causes errors in table generation function of sh bgp
ipv4/6 unicast neigh <ip> received-routes and simmilar (handled by the
same shared code) commands. The errors actually means that there is
incomplete records because the cut part is missing (it might be
beginning of the first record or the end of the last record).

Also URL generation for modal windows was simplified.

Refactor URL generation aparatus in decorator_helper to simplify linking
modal windows.

Bugfix BIRD graph parameters unwanted spreading/copying.

Slightly refactor the BIRD config and RT table parser.
Graph bindings are based on but less complicated than Cisco ones.

Refactor bgp_graph_gen function and subfunctions.
Add sh bgp ipv6 uni command with BGP graph decorator.
Add label escaping and vertex ID transformation in order to avoid
forbidden colons in the vertex ID. The colon char is a separator of values
in the pydot interface or so.

Rework parameter passing from
(result,router=0,decorator_helper,resrange,...) to more compresehnsive
version (session,decorator_helper). The session contains or should
contain all the parameters needed but there is a certain indirection
because session is being defined later in ulg.py. The rationale is that
even thouhg ulg.py can no be imported into files containing decorators
it is stable part of the ULG and therefore it might be used for building
decorators based on classes defined there (even though the classes are
not directly accessible, which can be overcomed by passing instances or
using decorator_helper to do needed class instantiation.

Modules for BIRD as well as Cisco has been changed to reflect this
changes.

Fix some woes in Cisco regexps.
Fix minor display bugs.
