Bukkit

1) Update to support 1.5.1 Bukkit beta.
2) Fixed multiworld support to disable XP Bank signs, no longer blocks all signs.
3) Removed plugin update check, will work on better solution for next version.
* check http://dev.bukkit.org/server-mods/blxp/#c80 comment.
4) Added /xpclear command to clear player XP Banks.

NOTICE:
"/xpclear (player)" will only remove their XP Banks, not signs and wont restore XP, only use if data is bugged.

/xpclear (player) sign" plugin checks all the signs from "world" (default world) and tries to remove them then return XP, but using this command IS NOT RECOMMEND, its very heavy and might cause crash on larger map. These commands were done by request and will be improved in next update.

Adding XP by clicking sign feature is still under development, currently will not deposit all of your remaining xp with the last click.

IMPORTANT!  Read http://dev.bukkit.org/server-mods/blxp/pages/faq/ if you are Essentials or WorldGuard to block creeper or/and TNT block damage!
