Fix for showing colors for priority and target date on dashboard
An attempt to consolidate some of the form handling JS

Including different JavaScript on different pages has it's advantages,
but I think that in general, it's less confusing when the same scripts
are on each page. I've created a main.js here, and I'm using require.js
to include the form code. I did this to fix the 'undefined method'
errors from jshint, and I think it will be a good way to organize
things.
