BRAKING: Rewrote configuration handling
MyWarp now defines an interface that provides an abstraction-layer for
all needed values. The actual configuration handling is done by
implementing this interface.
The conversion of the old configuration file (properties) has been
removed for now.
Constructors taking ConfigurationSections in ValueBundles have been
removed, since they enforce a strict dependency on the configuration
handling mechanism that is no longer exeptable.
The configuration-file has been reformatted and users need to
reconfigure it.
Pushed Bukkit to 1.7.9-R0.2 in pom.xml
Removed '/warp accept' in favor of conversion API usage.
