LP#1642086 TPAC Jquery path repair, .gitignore, karma

* Repair JS path in TPAC jquery import.

* Tell git to ignore Open-ILS/web/js/ui/default/common/build/ since it
  only contains generated files.

* Add jquery to Karma unit test dependencies.  This is not strictly
  required, since angular includes a slim jquery shim, but having the
  unit tests load the same base JS as the UI is probably best.
  Confirmed tests still pass.
