[patch]separate display and edit mode for form widgets

[bill]

1. Currency

When displaying a currency textbox it should look like

$123,456.90

but when editing the $ and , should disappear so it looks like

1234568.90

(note that it should still display the decimal as 90, not just 9)

2. Number text boxes Similar to above

3. Infrastructure General infrastructure to support separate edit and display modes

use optional editOptions property to mixin special edit pattern

fixed in [11710]

(In [11712]) Back out [11710], refs #4511. Doesn't tolerate bad input at all for some reason. Also, it would be nice to tolerate (but not require) symbols and separators in input.
