ExploreRegion: Fix encoding X and Z

Browse Source 
Use a long to store the two ints (x is upper and z is lower) - this is guranteed to work with any world map size out there.

It also properly handle negative values that the old implementation some times did not properly manage.

This might use slighly more RAM, but should provide support for actual infinite / huge map sizes
