Account transfer cleared dates

A "Transfer Cleared" date has now been added to the bank transfer page.  This is based on feedback from clients who's bank does not do same-day-transfers.

You can now specify what date the funds left the account and what day it arrived into the new account (cleared date).

Bank transfers should be recorded when, for example, you have multiple business bank accounts (e.g. current & savings) and you move funds between these accounts.
