Replace *CellDraw classes with CellFormatting functions.

This fixes rendering and crashing issues in (Rom|Game)Grid with mono.
Need cellbounds to be the full wide and not just the visual.
Move (Rom|Game)Grid CellFormatting functions to be in the right #region sections
Make drawn text look better in GameGrid's CCorrect
GetFiles() for mono was missing initializing the Length
chdman fixes for mono/unix

- call chdman as chdman and not chdman.exe
- fix parsing issue with chdman stderr output
Fix parsing of chdman stderr output.

Makes it works under mono/linux and also corrects the displayed error
message in windows.
More CHD related fixes

- CHDReturnError was not handled and would cause an exception/crash
- CHD error/filename were swapped in ErrorGrid when scanning
- Use regex when parsing chdman stdout output
Additional Mono rendering fixes

- on initial rendering mono likes to send a resize event where the width
is 0, ignore it.  This was causing gbDatInfo to not render until a
manual resize was done.

- set AutoScaleMode to System.Windows.Forms.AutoScaleMode.None.  This
fixes a number of rendering issues under mono and didnt seem to have any
negative effect under c#/windows builds.

- tweak some of the initial form sizes and locations on FrmMain.  A
number of the setting didnt make sense based on the size of the panel
they were put it.  This resolves an issue with the gbDatInfo and
gbSetInfo starting off with the wrong size under mono.
ui rendering fixes for progress window

FrmProgressWindow.Designer.cs was setup for the windows being 591 wide,
but rv was forcing it to be 498 when the window was brought up.  This
was confusing mono and it was causing rendering issues.  This patch
makes it so the Designer and rv agree on the width of the window.
Additional adjustments were made to standardize the spacing between
window edge/progress bar/button, resulting in a width of 511.
Force all pTree.Tree.RTree to have aleast some width.

This fixes ToSort not having the "└" in the tree view.
speed up populating GameGrid

These changes speed up how long it takes to populate the GameGrid after
clicking on a dat in the Tree.  MAME 0.155 dat was used for testing.
Before the changes population times were

windows .net = 2.75 seconds
linux mono = 23 seconds

After the changes, both now take 300-400ms.

This was done using 2 main changes.

1. Fully move populating the rows' Values to the CellFormatting function
2. Determine the total number of rows we will need and use
GameGrid.rowCount to set the row count to that.  This is much faster
then doing individual Add()'s for each row.
