Merge pull request rentzsch#46 from vguerci/mogenerator

---

This pull request allows to put `xmod` tag on a versionned model *(.xcdatamodel**d**)*
Script then will automatically detect current version and call `mogenerator` on it.

This modification is non intrusive and not breaking existing behavior.
This is a popular request related to several issues : rentzsch#7, rentzsch#14, rentzsch#37

Thanks to nvie who this is largely inspired from : nvie/mogenerator@575584320a03f8738f9e1c42f6e05f865f8aeb5a
