Updated plugin, added comments at the top of the code that say I'm the author 
of the plugin and that place the plugin under GPL. Added text to the loader 
message also saying that the plugin is under GPL.

The regex that extracts the HP/SP/MP tables is now read using a lookup table 
at the top of the script. This should allow players of multiple muds to more 
easily make it work with all of their chosen muds. An example entry is 
provided to show them how to do it.

I was working on code to keep a seperate player-state object for each 
connection. But apparently every time the connection is handled to python, 
it's a different object even if it represents the same connection. I suggest 
we look into some form of connection-unique ID number or a 
connection.equals(connection2) method.

For scripts to handle multiple connections at once, this may well be a 
necessity, host + port alone are not unique enough (multiple connections to 
the same MUD are possible). I'll look into this myself but any advice on 
where to start would be appreciated.

I also suggest moving the methods under 'Useful shiznat' into the GnomeMud 
module, and there are two other methods I have written that are also worth 
adding (ttoi and makeAnsi). These provide methods for things many scripters 
are likely to want to do. I'll look into how we might do that aswell.
