Merge pull request #1 from Derenhein/develop

Well, this release adds some features on customization css styles, adds new css styles, adds few more methods for games bases on Xd6 system with wild dice, BRP utility for confront two ability scores, a dice roller for Vampire: Dark Ages (1996 first edition), some tweaks and improvements.
As i don´t have more games to develop tools on this library, and i doubt it will be widely utilized, the next updates will be fixes, update readme.md and docs.

P.D : Updates on grunt file. more helpful to build min files and debug.
