Run TP without installing sphinx

UPDATE: This should be taken care of with this commit

Now you should be able to run TP in development mode without needing to have sphinx installed.

It’s not trivial to install sphinx and get it running on your local machine so here are some instructions to install and run the TP app on your local machine without the need to install sphinx. If you don’t use the search functionality in the front-end you should be fine.

1. Comment out the gem depency in config/environment.rb
#config.gem "thinking-sphinx"
http://github.com/jhilden/talkingpoints/blob/master/config/environment.rb#L25

2. Remove the inclusion of the thinking-sphinx rake tasks in the Rakefile
#require 'thinking_sphinx/tasks'
http://github.com/jhilden/talkingpoints/blob/master/Rakefile#L12

Please add any additional changes that you needed to make
