bugfixes to teh previous commit... cleaner exit for the indexing thread

Added a flag for indexing threads so that they exit once Metacat has unloaded.

Modified the way checkDocumentTable is accessed. Also removed the while loop from the checkDocumentTable. Now if the document is not found, the thread goes to sleep - instead of checking again. (In hope of a more bugfree code)

A version with less number of bugs.

New code for run an indexing queue and indexing thread which runs every 24 hours
