AlliedModders - [TF2] No Shotguns in BBall

This is a plugin that gives you the option to disable shotguns on any maps with "bball" in the name. Most of the credit for this plugin should go to the authors of these two plugins (I kept their names in my plugin):

I modified the weapon restriction code from the "only-melee" plugin to only remove slot 2 (the shotgun slot), and I took the keyword recognition for map names from the "jump mode" plugin. Tweaked that a bit and then I was done. Not bad for only taking a semester of freshman comp-sci a few years ago :)

Convars
sm_noshotgun 0/1 - Defaults to 1 and allows you to turn off the mod if you wish (by setting it to 0)
sm_bballmap 0/1 - Is set by the plugin whenever a new map is loaded. If the name of the map contains "bball", it is set to 1, otherwise 0

Both convars have to be "1" in order to disable shotguns. Note that the plugin really disables all slot2 weapons, but bball is only played with soldiers and I'm only writing the plugin for people who intend to play the map that way. Also, if you enable/disable shotguns during a game, it won't take effect for each individual person until the next time they respawn.

I've tested this plugin on my local machine and on a friend's server and believe it to be working fine. This is my first time doing anything like this, but I believe I covered all my bases. Please let me know if I'm missing anything!

EDIT: Almost forgot, a big thanks to Mooga for helping me out with sourcemod and all the noobish stuff I needed to know, and Revalk for use of his server!
