fix sorting on GameGrid

Browse Source 
When switching to Cell_Formatting to fix rendering in mono and also provide
a speed up to displaying the GameGrid, it broken sorting on the CGame and
CDescription columns.  This is because we are no longer setting the Value
field on those cells.  On windows, clicking those column headers would do
nothing, under mono it would cause a crash.

Instead of reverting the Cell_Formatting change, this update make us handle
the sorting ourselves.  Mono doesnt implement SortCompare, so had to handle
column header clicks and make our own IComparer.

This also disables sorting on columns that are images, including on RomGrid.
