1. Grid cell defaults are now handled by an internal

Browse Source 
wxGridCellAttr object

2. wxGridCellRenderer::Draw updated to expect an attr object and
use it instead of going back to the grid for everything

3. The selection colours are now initialized from wxSystemSettings,
and are configurable.

4. Now either CreateGrid() or SetTable() can be called to initialize
the grid.  Added a test for using a non-default table.

5. Reduced flicker even more byt using empty EVT_ERASE_BACKGROUND handlers.

6. The beginings of wxGridCellEditor are in there but not activated
yet. (This is the next step.)
