[Feature] Add Comment to Item Data/Quest API (#3669)

* [Feature] Add Comment to Item Data/Quest API

# Perl
- Add `quest::getitemcomment(item_id)`.
- Add `quest::getitemlore(item_id)`.
- Add `$questitemdata->GetComment()`.

# Lua
- Add `eq.get_item_comment(item_id)`.
- Add `eq.get_item_lore(item_id)`.
- Add `item:Comment()`.
# Notes
- Added the ability for operators to pull these fields from item data without a database hit.
- Fixed a bug in `embparser_api.cpp` where `GetZoneGravity` was connected to the wrong methods.

* Update embparser_api.cpp
