[Libreoffice] HC Cleanup

[Joseph Powers]

While creating the HC Icon set, could you look into the following?

default_images/svx/source/svdraw
	cropmarkers.png			-  2d icons for cropping
	cropmarkers2.png		- 3d icons for cropping
	cropmarkersACC.png		- HC icons for cropping

	markers.png				- 2d icons for markers
	markers2.png			- 3d icons for markers
	markersACC.png			- HC icons for markers

The ACC versions will need to be copied in the 2d & 3d version in the HC set. I've removed the code referring to the ACC versions.

--------------------------------------------------------------

Just to confuse people, I changed the Auto-Detect HC mode option to change the default theme to the High Contrast one. Yes, I know that when changing the OS back to a normal theme, I don't change LibO back to the old theme (we currently don't have a place to store the option).

I changed the Windows Only code to match this behavior; however, I don't have access to a Windows build system so the change is 1) un-tested & 2) theoretically correct. Any testing would be great.

--------------------------------------------------------------

It should now be save to remove all the HC versions of the icons from all sets and start packaging the HC set as it's own theme.

PS: I believe I've removed all the code dealing with loading HC version of Icons. If no-one objects, I'll remove the task from the Easy-Hacks page.
