wish: Auto-add decimal point for quicker data entry

[Chris]

When I have a lot of transactions to input, I could enter 12598, and my adding machine and other software has the option for that to be interpreted as 125.98 automatically. I believe GnuCash handled it with a setup option.

If I have a transaction of 0.37, I have to hit two extra keystrokes - extra typing, all for a measly 37 cents. :P

Also, it would be nice if hitting the minus operator while there are numbers in the text field would still work. At present the field has to be empty, so that the minus is the first character in the field. Quicker data entry could come from having the minus key act as a toggle switch, similar to clicking the +/- symbol with the mouse; only.

Apologies if this is a dupe wish, I didn't find any duplicates.
