Reindex tweaks and improvements

Browse Source 
-Added an "Are you sure" prompt before starting the reindex to make it clear that this is a destructive sync option
-All necessary coin stat data is cleared before starting the resync (txes, blockchain_last_updated and richlist_last_updated were not previously being cleared)
-More and better messages about what is being done during the process
-Shifted some of the code around to be run in a better order (for example, blockchain_last_updated date is set right after finishing the blockchain sync instead of at the very end of the reindex)
