[text-field] Add support for input formatting

[juuso-vaadin]

Automatically format entries according to defined rules. Add decimal separators, spaces, characters etc.

For example IBAN number: DE89370400440532013000 → DE89 3704 0044 0532 0130 00

Monetary value: 645064 EUR → 6,450,064.00 EUR

Will it be done?

it's very important to have a native way to put a DecimalFormat or some way to validate the data typed.
