Strip , and $ from amounts before evaluating them in amount fields

Allow the pasting of amounts with a , and $ by stripping them out before evaluating for errors.
I cannot copy $1,773.46 and paste it.
Instead, I have to edit it to be 1773.46
Defeats some of the utility of a computer.
I am sure there is code out there you can re-use as most websites do this.
The same for phone numbers.
