Pulling latest from master
Deleted Unused PHP Scripts
Fixed misplaced decimal during trans create

Changed AddTrans() amount parameter to int because as double it was
appending .0 to the end of all int values passed to it.
Changed db_transaction_create.php to take amount values as int without
decimal (ie $6.00 is '600')
