Multiline text fields?

[nullium21]

Is your feature request related to a problem? Please describe.
Was trying to make a simple script editor UI, but didn't find any text field widget with multi-line text support (line breaks).

Describe the solution you'd like
Either a WTextArea with multi-line editing and stuff, or that functionality in WTextField. From what I can see, the latter would involve at least a int maxLines field with a setter and a getter, some sort of line start -> offset map to be used in most methods using scrollOffset or cursor position, and some small changes in render* functions and event handlers.

Describe alternatives you've considered
Trying to write this myself.

Additional context
By, essentially, copying-and-pasting WTextField.java into another file and editing out the forced height of 20px I got it to render a box, but it looks like some more sophisticated adjustments need to be made to actually allow using those as multiline text inputs.

Text editing - especially multiline - is notoriously painful. For that reason, I don't have the energy to create a multiline text area for LibGui. If someone wants to contribute such a widget themself, I'll definitely merge that PR though.
