initial pg_search setup
Merge branch 'master' into dhoss/issues/28/pg-search
searches with no results present the correct form, as well as initial search page load
committing to make sure I don't lose anything before I possibly destroy this VM's hdd
moved migration for fuzzy search and trigram to sql file since they need to be run as pg super user.  added pg_search initializer
updated .travis.yml to attempt to install trigram and fuzzy search extensions prior to running tests
removed trigram search option, using tsearch seems to do fine
fixed up trigram support
Fixed #28. added link and changed from .searchable since it's now a native post object
