Better user notification upon perms not granted

Instead of making a status notification that fades away, make an alert
box which the user must consciously dismiss to say that permissions are
needed, and then make a status notification saying settings not saved.
Style. My preference.

Update jquery version.

buggy. Hopefully this one works fine.
Fix for a prior fix.
Use google's Closure compiler for .js files
