improved text-box

[kWeglinski]

0.14.0

• Fix: enforce font color (chrome bug) on text-area, based on theme. No more dark text on dark bg
• Feat: moved to rich-textarea library to not re-invent the wheel on text area styling.
  This also allowed:
  • Better styling for error highliht
  • Additional tooltip with quick peek of the issue and and quick (up to 4) click to fix resolutions (sidebar gives more options if language tool provides)
