Add wxGridSelection::SelectAll() and use it in wxGrid

Browse Source 
The difference between calling SelectAll() and SelectBlock() with a
block covering the entire grid is that the former discards any
previously selected blocks, which become clearly redundant.

As a consequence, clicking on the grid corner 10 times in a row still
results in a selection with a single block, not 10 (identical) blocks.
