Bug 389867

When inputting an amount for a transaction, I sometimes am copying that value from another window. If I am entering a transaction for $110.51, for example, I may write "110." in Skrooge's Amount field, and then switch to the other window to check how many cents to enter. When I come back, the decimal point at the end of my amount has been erased because Skrooge automatically cleans up entered values as soon as the Amount field looses focus. This also means if I enter an equation, such as 8.21 + 2.13, and I change focus after typing the plus sign, the Amount will be shown as a red error.

I have learned to work around this by not typing in the decimal sign or any trailing zeros if I know I will need to change focus, but it's not ideal.

Here are a few options that I feel would work better:

 * Turn off automatic changes to amounts, and show an error if  I try to save an operation where the amount cannot be recognized
 * Delay the automatic calculation of the Amount field until "Add" or "Modify" is pressed
 * Delay the automatic calculation of the Amount field until another field in Skrooge receives focus
 * Recognize values that may be incomplete and do not alter them. I'd be fine with them showing up as red like the incomplete equations.
