Rspec: Test 'Like' functionality.

[natsteinmetz]

When a user presses the 'heart' icon within a resource panel, the count goes up by one. If they press it again, the count goes down by one.

For now this is cookie based, so technically a user can still like a resource multiple times by clearing cookies, switching browsers, etc. This is a known restriction.
