Railgun Blast 2.1

/* ========================================================
* - NAME:
* + Railgun Blast
*
* - DESCRIPTION:
* + This is a fun plugin that adds a 'conc blast'
* + to the hit point of the railgun shot.
* + When the shot hits a wall/player/etc it will
* + create a 'conc blast' and bounce anyone
* + within the radius a certain distance away
* + depending on how close they are to the explosion.
*
* - CREDITS:
* + The old TF-Tech mod for giving me the idea.
* + TKG for helping me create a new push function.
* + Ramono for letting me know to register the entity with a touch.
*
* -------------
* Server cvars:
* -------------
* - railgunbounce <0/1/2>
* + Setting to 0 will turn the railgun blast off.
* + Setting to 1 will turn the railgun blast on and bounce everyone.
* + Setting to 2 (default) will turn the railgun blast on and bounce only you.
