Implementation of multiline texbox with selection and vertical scrolling.

Implement the multiline textbox selection and scrolling

• any portion of the text can be selected
• the text scroll vertically as necessary
• the selection is properly visualized per line.
• If a "word" is too long it will be wrapped on sub-word character. (as in any editor)

However: I specialized the render function of the multiline textbox, there is pbly a way to have better perf.

And ... it should maybe be re-implemented using the scroll area, since a scrollbar is very handy for a scrollable text box. However that's a design decision, let me know what you think...

Should be fixed now.

Thanks. You'll probably have to redo it all now as GWEN as been reformatted. Not quite sure what the point of that is when there seem to be so many issues outstanding. I imagine all outstanding code patches will now have merge conflicts.

Well, I'm assuming that's one of the reason why it haven't been merged yet ^^

Yeah sorry you'll have to merge in the code changes from the main branch so I can easily merge this in.
