OnLClicked - overloaded CUGCellType::OnLClicked
Checks to see if the spin button was clicked on.
If so, then it checks to see if it was the up or down
spin arrow.
If the up arrow was clicked then a cell type event
is fired: UGCT_SPINBUTTONUP
If the down arrow was clicked then a cell type event
is fired: UGCT_SPINBUTTONDOWN
The value within the cell is not modified, this must
be done during the cell type even. The reason for this
is to allow the spin control work with any data type
rather than just numbers.
