Buddy block doesn't update it's texture properly.

[Tekei]

When placing a buddy block the texture gets stuck on "on" and won't update back to "off" until I place a block on top of it (next to it on the sides won't work. Once it goes back to "off" it won't show the "on" texture again.
This seems to only be a graphical glitch as it does power redstone properly as far as I can tell.

Fixed for next release.
