Changed our nested query search logic to use straight-up edismax.

Ho-ly crap that was easy. THAT'S WHY WE REFACTOR STUFF EVERYBODY. THANK YOU AND GOOD NIGHT.
added in query fields for actors, genres, etc
added poll placeholder sizes to the model and used them in <img /> tag as its attributes
removed sizes from scss because we use them in <img /> tag now
renamed the method and one variable
removed part of code which was not executed at all -- it was a wikia poll placeholder which now is rendered by WikiaPoll hook method
change after code review: it is better in performance terms not to create stdObject just to return width and height values; removed getRtePlaceholderSize() and added two small getters instead
removed boost query string and boost functions
refactoring config to have rigid rather than fluid properties, handle query service selection
updated code to get it working, now need to test
removed undesirable boost queries from interwiki
tests now running but failing
remove AutoHubsPages from repo (BAC-170)
get unit tests building complete, need to revisit several tests
BAC-239: s/bulid/build/g  fix typo
* initial version of test file
* fix syntax
VID-232 Updated script to take i18n into account
Merge branch 'dev' into improved-videosearch
introduce VET query service apart from Video search
