added new cask intellij idea 14 EAP

I created this cask file to embed intellij idea ce v14 EAP for the following problem:

http://stackoverflow.com/questions/24633529/classcastexception-apiversionimpl-cannot-be-cast-to-java-lang-integer

So IntelliJ Idea 13 contains these errors again and not the v14 EAP.

Have fun to benefit about this cask ;)
