Changes

#4 was implemented as a functionality again (previously seen in vip-australium).
- Players can now override their melee weapon with either The Golden Frying Pan, The Saxxy or The Golden Wrench
- Overrides set on your melee weapon will be transferred to your overridden melee.
ConVar support is now implemented.
- tf2items_general_onlyspawn controls if users can utilize both plugins only on spawn regions.
- tf2items_cosmetics_show_missing_particles spews debug information whenever an ID without translation phrase is added onto a menu.
- tf2items_cosmetics_unusuals toggles the Unusual Overrides from the Cosmetics Manager.
- tf2items_cosmetics_paints toggles the Paints Overrides from the Cosmetics Manager.
- tf2items_cosmetics_spells toggles the Halloween Spells Overrides from the Cosmetics Manager.
- tf2items_cosmetics_append_ids appends the Unusual Effect ID onto its name (for ex.: Burning Flames (#13))
- More ConVars will eventually be added if needed.

tf2item_weapons

Fixed weapons with the saxxy classname not being given properly, and causing crashes on rare occasions. Would fix #5.
Fixed slot indexes not being checked (would set melee weapons on 2nd slot if a 2nd weapon wasn't found, like having the Gunboats)
Optimization tests.
Implemented ConVar support.
