[MC-26] (Cobble)stone wall graphics are glitched

Cobblestone walls that are attached to something have reversed vertices or something like that.

Environment

Windows 7, x64, latest java (1.7_03 or something), I used magic launcher to launch minecraft but it's the same under the vanilla launcher.

Sorry, I didn't see that bug report.

@Stijn: No problem. I expect – given successive numbers – we were writing them at the same time.

Also happens to fences
