Improved and Renamed CommandRegenPocket

Renamed CommandRegenPocket to CommandResetDungeons. Changed command name
accordingly. Added a message for the user listing the number of dungeons
that were reset. Modified DimHelper slightly to add support for this.
Added error condition if user specifies arguments for the command.
Improved CommandPruneDimensions

Improved CommandPruneDimensions. Cleaned up the code and improved
performance by using a HashSet instead of an ArrayList to list dimension
reachability. Added an optional argument that sets whether we should
delete the folders of pruned dimensions.
rewrote schematicLoader

Temporary Fix to Commands

Temporarily patched up CommandDeleteAllLinks,
CommandDeleteDimensionData, and CommandDeleteRifts so they'll compile.
I'll be fixing some things for Steven and I'll come back to those
classes to finish overhauling them.
Fixed Rotation in SchematicLoader

Fixed reference to CommandRegenPocket - should be CommandResetDungeons.
Autofixed indentation in SchematicLoader. I wanted to commit that change
before doing any more code changes but I forgot. Then I fixed the code
that calculates the coordinate offsets so our dungeons rotate right. It
was pretty simple - all I had to do was move the xCooe and zCooe
calculations into the loops so they're recalculated to account for
rotation. I rearranged the loops for optimal performance.
