Title: ASGARD-297 - better select boxes 

Replace all select boxes (single or multiple) with the [Select2 library](http://ivaynberg.github.com/select2/), except for the region select at the top of the page.

Upgraded jQuery components to 1.8 as part of this change.

Switched to use Select2's placeholders in places where we were using `g:select` tags with a `noSelection` entry.

The toggling of the VPC select boxes for security groups, zones, and load balancers required some programatic manipulation of the select2 components.
