Tweaks/Fixes to the cards.

 -Changed [CUSTOM] to [C] to reduce clutter.
 -Fixed "r/MLPLounge" expansion to it's proper name and home. (It in no way *ever* belonged to /r/mlplounge.)
 -Fixed "Ponies with fucking lasers on their heads." card. (The [reference](http://www.imdb.com/title/tt0118655/quotes?item=qt0367888) was mangled when I originally made this card.)

I'll probably be submitting a new pull request within the month for more fixes to the CAE expansion, there were a few things I muddled up and I don't know what's been fixed yet.
