Fix parameters for SyncIt_ServerPersist_MongoDb.getLastQueueitem() and fill in a errors code for in _getLast() - This STILL needs a lot of work
Check that it is valid to go from State A to State B
Change some statuses to be slightly more sane in SyncItTestServ, this will enable browsers etc to act accordingly when TRYING_TO_ADD_FUTURE_QUEUEITEM
Add a SyncIt.purge(dataset) method and also make SyncIt much more reslient to when LocalStorage has bad data (like having changes (pathitem) for a dataset/datakey but when that actual root record is missing)
