Update feature module to 7.x-2.x

Update feature module to 7.x-2.x

The 7.x-2.x version is very compatible with feature exports created from the 7.x-1.x version. However, User Permission features will need to be re-exported, and Field features will be split into Field_Base and Field_Instance exports the next time you export. See New Field Bases and Instances in Features for more info.

We need to recreate all features and check every site functions manually.
