"URL command" chat plugin for Tkabber.

I. The idea.

This plugin provides two additional "IRC-style chat commands",
which are  specially formatted chat messages, recognized as
commands to Tkabber. They are parsed and executed, then  their
text is thrown away (examples of standard chat commands are:
/clear, /nick, /ban, /leave, etc).

Provided commands are:
* /listurls shows the list of all URLs contained in the text of
  the current chat window;
* /browseurl opens an URL with the specified number in the
  browser.

II. Usage.

The syntax of the commands is:

/listurls

/browseurl ?n?

The argument surrounded by question marks is optional.  The n
argument of the /browseurl command specifies the zero-based
index of the URL  to browse. If it is omitted, the last (i.e.
sent most recently) URL present in the chat window is opened.

III. Examples:

Show the list of all URLs present in the current chat window:
/listurls

Open the first url in the list:
/browseurl 1

Open the URL that was sent to the current chat most recently: 
/browseurl
