Title: [WIP] Adds time tags to monster spawn groups

* GROUP_FOREST monster group is done.
* Removed chicken and sewer rat spawns from GROUP_FOREST, due consistency.

TODO:
* Finish others monster groups.
* Figure out why Giant spiders still spawn, as they are set to spawn after three days of game time.
