Update bank.simba

Updated co-ords for FixBank which was lagging the bank screen and clicking due to the old co-ords.
Updated WithdrawEx b/c it was clicking withdraw-X when withdraw-12345 was visible in the chooseoptions, it's still used if the option can't be found.
Merge pull request #134 from KrazyMeerkat/patch-2
