[GNC] Feature request - prevent a transaction with todays date

[Ken Farley]

"Go to a backup file" Why? You know you can change the date on a 
transaction after it has been entered, right? You can use the "+" and 
"-" keys to move up and down as many days as you want. The transactions 
are not permanently entered and unalterable.

About 90% or more of the transactions I enter are "today" transaction - 
payments, purchases, deposits, withdrawals, charges, etc. Not having the 
date default to today would be annoying.

If I enter a transaction and it's supposed to have been in the past, oh 
well it's at the very end of the register, the register opens up to it. 
I can just fix the date to move it to the proper region of the register. 
If I accidentally enter a transaction with a past date, it disappears to 
the past I'll only notice it if this happens to be an account I 
reconcile...maybe.
