Add custom painting and section handling to RDTableView & RDHeaderView

Browse Source 
* This is used primarily for the buffer/mesh viewer to be able to pin
  the index/element column to the left side, group columns together with
  a noticeable separator, and other minor tweaks.
* Unfortunately due to tight private coupling and lack of virtual
  functions in the QTableView and QHeaderView, a few unrelated functions
  have to be re-implemented to point to our own header.
