Mass update from memory stick:
* .gitignore - Add new directory present on memory stick.
* bulk.c - some bits and pieces.
* changePIN.c - start validating and add author.
* deposit.c - commit new function.
* orderStatement.c - commit new function.
* useCustData.c - get address.
* withdrawal.c - commit Tom's code.
Add exitATM.c - new function (with more TODO?) that shows log out data and writes stuff to a file.
Rework some of orderStatement.c (untested)
Add a new function, orderChequebook in orderChequebook.c. Pretty much a pointless function but it keeps menu.c clean.
