[Quest API] Add IsRaining() and IsSnowing() to Perl/Lua. (#2477)

* [Quest API] Add IsRaining() and IsSnowing() to Perl/Lua.

- Add quest::IsRaining() to Perl.
- Add quest::IsSnowing() to Perl.
- Add eq.is_raining() to Lua.
- Add eq.is_snowing() to Lua.

This will allow server operators to tell if a zone is currently raining, snowing, or neither.

* Remove unnecessary quest manager stuff.

* Added constants and cleaned up #weather command

* Revert "Added constants and cleaned up #weather command"

This reverts commit 2ec85304b7407bbd4acfcc0dd7e1e5710f7bce8f.

* Revert "Revert "Added constants and cleaned up #weather command""

This reverts commit 76f4e411b6239aec9e6c8945ede0656e5e2ad9c1.

* Delete settings.json

* Update zone.cpp
