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.
