Corrected handling of row/column attributes/selections if all columns/rows

are removed.
Emit EVT_GRID_CELL_LEFT_CLICK before doing any processing of the left click
        mouse event (instead of emitting it somewhere in the middle).
Moved calls to UpdateAttrRows/Cols to wxGrid's Insert/DeleteRow/Column
        (thereby eliminating the need for two now removed functions).
