Added jquery (separated from the 'project' version) and jquery-ui (used in job.php)
* lib/db.R:
  - Unified naming conventions: replaced all "insert" for "save" in function names.
  - Changed "grouping" of senses, so the order in the file makes more sense (min)
  - Changed save/get FilteredWorkers: getting rid of "null" filters: bad design.
  - Renamed getFiltSentences -> getFilteredSentences, to make it similar to getFilteredWorkers.
  - Refurbished saveWorkerMetrics to take filters into account.
  - Removed selectWorkerSentenceScore: it's  a simple Query, being handled by the simpleQuery function.

* set_analytics.R
  - Unified naming conventions: replaced all "insert" for "save" in function names.

* workerMetrics.R
  - Unified naming conventions: replaced all "insert" for "save" in function names.
  - Getting rid of "null" filters (see above). Changed "null" for 'disag_filters'
