Merge pull request #12 from Gecka-Apps/master

Directory name agnostic plugin dependency check, Fixes compatibility, fixes duplication of posts, fixes users connections
Really fixes posts to users & users to posts connections synchronization
Revert "Really fixes posts to users & users to posts connections synchronization"

Merge branch 'master' of github.com:Gecka-Apps/p2p-wpml
