The tooltip was showing a bullet point for an `li` element which was showing up on the outside of the tooltip box. Setting the list-style-type to none removes this bullet point and makes the tooltip look a lot cleaner.
- Project > Edit Board and Project Summary pages now show description as tooltip.
- Project > Edit Board shows textarea with markdown preview. Edit column also shows markdown preview.
- Fixed bug while adding a new column inserts description as column limit.
