Bukkit

Fixed a bug with signs not updating if multiple people are in the same area
Fixed the event system not working properly
Added unicode placeholder (more coming)
- {u:HEX CODE}
Included in v0.7.6
Signs now update on left click
Reduced the chance of a "Cannot locate sign X,Y,Z" client side bug.
{money} is rounded and no longer returns in scientific notation.
Vault is no longer required
- Many placeholders (which depend on vault) will not work if you don't install it.
- It will warn you when you enable the plugin if vault is not enabled
Rather than getting some severe exception, you are warned politely that the plugin is disabling itself if you do not have ProtocolLib installed.
