Fields should support these normalization options:

1. normalize NL (\n, \r\n, \r to \n - currently done always without option to set it on/off)
2. replace NL to space ' '
3. replace all white chars (\s in regex except NL) to single space ' '
4. remove all leading and trailing white chars
5. remove all trailing white chars in each string line
6. allow to exclude tabs (\t) from white chars

Used should have full control over all of these options and their combinations using one field property like normalizeText.

For non-binary fields all of these options except rule 2. and 6. should be on by default. In atk4/ui is makes sense to turn rule 2. and 6. on too for all fields except textarea.

Feedback and help with the implementation welcomed.
