#search.rb
Check for thing.present?, some search terms are coming back as an empty 
string, that causes the sql built to search for empty string on that
attribute

#user.rb
Add has_many for galleries, since the after create tries to add one

#users/_user.html.erb
If not logged in, current_user is nil, so don't ask if admin?

#users/new.html.erb
The second select is overwriting the first, if I am a man, interested in
women, my profile gets saved with my gender as 'women'. You should 
create another attribute on User to track this. I suggested
"seeking_gender" for this, but it is commented out so you can implement
as you see fit.

#.ruby-version
This is for RVM, Chruby, & Rbenv to signal that this app should run
in a Ruby 2.0 environment (as is specified in your Gemfile)
