patch applied (cabal): Use "pkg == 1.2.*" as the version wildcard syntax

  * Use "pkg == 1.2.*" as the version wildcard syntax
  Rather than "pkg ~ 1.2.*". This seemed to be the consensus.
  The syntax "pkg == 1.2.*" means "pkg >= 1.2 && < 1.3" and it
  is to encourage people to put upper bounds on api versions.
