Soocial should provide information on the time of last gmail sync request

For a gmail connection I think it would be useful to add information about the time of the last manual sync request whilst the sync is in queue but not yet executed.

Sometimes I have scheduled a manual sync and then some minutes later I come back to check if it has been implemented (only I forget which time I made the request) so it is unclear if the last sync occured before or after I made the request.
