Resurrect selections.
Update Gemfile.lock with canonical version ordering

https://github.com/carlhuda/bundler/issues/1375
Constrain Gemfile to Ruby 1.9.2

Several gems need upgrading for Ruby 1.9.3 compatibility.
Remove .rvmrc example

Bundler supports Ruby version constraints now.
Upgrade to ruby 1.9.3 and rails 3.2.

Asset pipeline isn't enabled, yet.

Have also upgraded most other underlying bits and bobs too.  Everything still seems to work, which is surprising.
Generate config for new version of simple_form.

Reconfigure it and fix our BlueprintForms stuff so that it uses a new wrapper type and our error wrapping still happens.
Get the build green again

Our markdown method returns '' instead of nil.  It breaks the transparency of the method (e.g. pass in nil, get nil back), but it makes it safer when used in our rss feeds, as apparently builder doesn't like cdata!-ing nil.

On the selection page we might be showing more than one instance of a proposal (your selections + top 10), so we need to prefix the ids to disambiguate them.
Ran rake rails:update:config
Asset pipeline baby!

Got rid of old prototype JS files, moved everything out of public and into app/assets or vendor/assets.  Added asset gems.  Made application.js and vestibule.css into manifests (and .scss in vestibule.css's case).
Gosh! What is this, the past? We don't need no vendor/plugins dir.
