Reversing the angular 1.2.0 upgrade because it breaks asset precompilation

JIRA: https://jira.media.berkeley.edu/jira/browse/CLC-2833

Christian will need to review this when he's back in the office, to make sure that I resolved the merge conflict in _myfinances.html correctly. And, of course, to see if angular 1.2.0 can be fixed!
