Title: Let -zapwallettxes recover transaction meta data

zapwallettxes currently loses wallet transaction meta data information like:
- vOrderForm
- strFromAccount
- nOrderPos
- ...

This pull stores all wallet transaction meta data before erasing the transactions,
and then restores this information after rescan. Only to those transactions being
recovered by rescan obviously.
