Improve performance of JTable by disabling kerning on table font.

Ensure lead selection border of tree cell  is painted last.
Added option to declare fallback values in properties that are only applied if the key doesn't have a value associated yet.
Ensure boolean renderers use the correct cell border.
Center boolean renderers.
Ensure DarkMultiCellEditor uses the correct delegate.
Fixed missing border on table header cell after scrolling.
