Modified Configurable Chunk Inhabited Timer Patch
Replaces the "use-chunk-inhabited-timer" config option with the options
"use-fixed-chunk-inhabited-time" and "fixed-chunk-inhabited-time".

When using "use-fixed-chunk-inhabited-time=false" everything will be the
same like it was with "use-chunk-inhabited-timer=true".

When using "use-fixed-chunk-inhabited-time=true" and
"fixed-chunk-inhabited-time=0" everything will be the same like it was
with "use-chunk-inhabited-timer=false".

Instead of just using 0 when all chunks should be treated equally this
allows to fine-tune vanilla gameplay.

Subject: [PATCH] Block Enderpearl Travel Exploit
Players are able to use alt accounts and enderpearls to travel
long distances utilizing the pearls in unloaded chunks and loading
the chunk later when convenient.
This disables that by not saving the thrower when the chunk is unloaded.
This is mainly useful for survival servers that do not allow freeform teleporting.
