- Coded @reset.

- Reenabled @changesex
- Added function pet_create_egg which handles creating pet eggs correctly (when passed item id is indeed a valid petegg). Applied this on @createitem and getitem.
- Cleaned up code of @item
- Added define UNKNOWN_ITEM_ID (512 = apple)
- Added IT_* enumation item_Types to identify said data from items.
- Cleaned up the itemdb_isequip functions. itemdb_isequip will now return if the item is equipable by players, itemdb_isstackable returns if the item can be stacked, and itemdb_isidentified returns if the item should drop identified.
- Added defines CARD0_PET/CARD0_FORGE/CARD0_CREATED to identify if a given item has "invalid" cards, added define function itemdb_isspecial to simplify this check.
- Removed itemdb.c considering item ids above 20000 as invalid.
- Cleaned up script commands getitem and card-counting related ones. 
- Cleaned up a bit more pc_isequip
