Fixed issue#14 and other Indeed Plugin issues

-- We were incorrectly setting title:(keywords) on every query, not
just title-only matches.  This caused title-only matches to actually
include title:(title:(keywords)) which would fail to return results.
Now fixed.

-- Also now set C__JOB_KEYWORD_SUPPORTS_QUOTED_KEYWORDS for Indeed
plugin.
Fixed:  another invalid function call if no results returned for a run (needed to check null and 0 case)
