- Applied a modified version of Karate Chris's screenshot naming patch.

- Sbarinfo optimization: Creating and destroying bar textures every frame is a relatively expensive operation. We can skip the custom texture entirely and just draw the bars directly to the screen, using the clipping parameters for DrawTexture(). This also means bars are no longer limited to the game palette, and the bar itself has the same resolution as the screen. SVN r731 (trunk)

 - Removed support for numeric flags from sbarinfo's drawmugshot command since
-  it was declared unrecommended and deprecated.
+  it was previously declared unrecommended and deprecated.
 - Added Blzut3's sbarinfo update #10:
  * Fixed: drawmugshot now adjust to the player's max health like it should.
  * drawgem can now accept negative paddings.
