Title: Localized number input

This will enable a localized input for decimals.
Define your localized number format with number.format.separator
and number.format.delimiter.
For a German locale this would be:

de:
number:
format:
separator: ','
delimiter: '.'

Now you can enter numbers like 1.234,5 and it will be parsed
correctly according to your locale.
