Read-only TextField mode

[czyzby]

This is a feature request. It would be nice if you could use text fields and areas in read-only mode, where the user can select and copy the text, but is unable to paste or enter anything. This would be very useful for displaying informations that might need to be copied, but should not be possible to change even by mistake: like stack traces. This change would probably affect most of the listeners attached to text fields.

If this gets introduced, as separate style (text-only?) without background could be added to text fields, so you could create "selectable labels". While not necessary, it would certainly be convenient.
