Fix Jasmine tests - first pass

193 specs | 5 failing

The 5 failing specs appear (according to Firebug) to be due to missing
fixtures and/or missing routes in the Jasmine environment. Fixing these
last 5 failures is a task probably best left to a more experienced
Javascript/Jasmine developer.

This commit also moves validation.js and clear-form.js into
app/assets/javascripts and precompiles validation.js
