Bukkit

• Option to prevent ops from modifying areas protected by '-admin-'
• Special use of playername '-admin-' in the protections file
• An op should receive a message if they are altering protected blocks
• Allow an op to destroy a player's protected area
• Fix a bug where player commands throw exception when issued at server console

When a BlockPlaceEvent is cancelled (i.e. player attempts to place a second bed), the 2 block of the bed still appears to be placed. I believe this is a bug in Bukkit/Minecraft. See this issue in the github page and this forum post for more details.
