Remove extremely verbose debug from Cisco graph routine.

Improve header styling and table spaces.
Prepare for coloring even/odd rows.
Prepare for interactive tables (columns hiding).

Align the form parameter input to one single line.

Remove constants out of code and add error message to output when there
are no data produced by the show bgp ipv4/6 <prefix> command parser (or
BIRD equivalent - show route <prefix> all) and therefore no graph
can be generated. The error occures in situation when wrong prefix is
on input or the prefix has no paths in the routing table.

Update form style in order to fit all the dropdown boxes in a single line
if possible.

Fix Cisco graph generation routine that was broken by the previous fix
of the ASN parsing and decorator functions.

Fix ASN matches and decoration for sh bgp ipv4 uni ... *.

Generalize DecoratorHelper.decorateASN() function to accept formats
AS<number> or simple <number>.

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.

Add Debian installation section with Debian-specific package names.

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.
