enrollment validations v0.9

This is like a beta test version of enrollment validations. It adds css to highlight bad fields, uses Rails validations to check for the presence (if applicable - only when they explicitly send so incomplete applications being saved for later don't complain), and a locale file for making the error messages less awful.
I think the confusion on my end comes from overloading the save button to handle to different actions.  One is submit and the other is save.
