Reverting console using UIText due to missing multiline support.
Work towards multi-line support for UIText:
 - Fixed an issue with TextLineBuilder losing trailing newlines
 - Fixed an issue with applying styles to widget sizes
 - Made readOnly a layout option for UIText
 - Added max size calculation for UIText
Fixed offseting mouse clicks within interaction regions.
Merge branch 'develop' into fix_scrolling
