Update to angular 1.2.1

This updates the version of angular to 1.2.1, including related files like mock, animate, etc.

All seems to be working well, but on unit test fails. I removed it in with the https://github.com/geoadmin/mf-geoadmin3/commit/39c90d0301ec95a23d0a07983e542449a8c7c1d0 commit.

@oterral can you have a look at the unit tests that fails? (Uncomment the things i commented in last commit)

To be merged after deploy today.
