Add temporary kludge to prevent search kick from being double loaded.

In develompent mode, due to how refinery and Rails' autoloading works,
all the refinery decorator files are loaded and then reloaded on
launch. This causes a problem with searchkick complaining about already
being loaded. This hack prevents searchkick from being loaded more than
once in development mode. Need to find a better solution :-(
Use ransack alias to avoid conflict with searchkick in projects search.
Make search results page clearer.
