When chat event hits an UnknownFormatConversionException which requires better chat configuration, the quick dirty fix of setting chatTagInsertIndex to 0 is now automatically applied.
New conf.json setting "spoutTerritoryDisplayPosition" to set the screen position at which the current territory is shown. 0 = disabled, 1 = top left, 2 = top center, 3 (default) = top right.
Moved all integration code to separate package, ofr better code organization. Also moved EssentialsChat integration code out to separate file in there, allowing us to safely remove our copy IEssentialsChatListener.java file (which is otherwise needed to prevent a nasty NoClassDefFoundError).
