Add question text to the table and reshuffle specs

Modify the existing migration to include question body text. Since no
meaningful data is being collected, it makes sense to just modify the
existing migrations.
Add in grunt-connect-proxy to connect frontend server to backend

grunt-connect-proxy configured to proxy calls to the api to the port
hosting the Sinatra API (Shotgun). This allows use of 'grunt serve' and
'shotgun -o 0.0.0.0 -p 9393'. Change ports as necessary for use within
Vagrant - ports currently configured for use on local OS X machine for
speed.
Test view using JQuery Layout

Trying to implement a hidable sidebar.
Fix issue with scope of sidebar and editor

The scope is now shared between the main editor and sidebar, so
callbacks are no longer necessary.
Change question buttons to dropdown style

In preparation for addition of modal windows.
Implement modal window for question deletion

The current implementation passes the question to operate on back and
forth - this seems unnecessary. Check for a better way in the future.
