Improved debugger video performance (#800)

Removed very slow BitBlt() GDI calls in PrintGlyph() - now 18x faster in Release config!
. Replaced GDI call FillRect() with new FillBackground()
. Added missing bitmap declarations in GetDebuggerMemDC()
Fixed AdditionalIncludeDirectories for Debugger source files
