Increased default padding for fill and trim commands to 208 (13 chunks)
The /wb reload command works again
Added 1 more "safe" and 1 more "painful" block type for safe location determination, from newer 1.9/1.0 blocks
It now makes sure the target chunk is loaded before trying to find a safe Y position for target "inside the border" locations
Updated world folder location method for "trim" task to use new safer World.getWorldFolder() method
Added "The End" world support to the "trim" command, since those worlds have different region folder structure
Player teleports are now monitored and (if necessary) redirected inside the border; sadly this doesn't prevent the original target chunk from being loaded/generated (which would be nice if it's outside your border), but at least the player never ends up teleporting outside your border now for even a fraction of a second
