Title: Fix minor server authentication bugs...

1. If password is incorrect, user is not prompted to save corrected mb server because port is passed as -1 - but it checks it against server port setting but we now use SSL for authenticated webservice calls.
2. If user changes userid or password, reload collections
3. If user clears userid or password, clear collections.
