Bukkit

Now fully works with 1.7.2 and 1.7.5 (Offline players will not be supported in 1.6.4)
Fixed some imports. New placeholders:
- {location} and {location:player} which will return a string list containing the location
Fixed some existing placeholders returning the wrong value.
Fixed a bug where having multiple players in the same are would prevent the signs from updating.
Fixed a bug with placeholders longer than one line sometimes cause an exception
Fixed a bug with if statements comparing strings when it shouldn't
Fixed a bug with comparing strings not returning the desired result
Fixed a bug with 12 hour time not being entirely correct.
