Default player items and shared items are no longer capable of being duplicated regardless of item flags. Shared items now give a true copy of the item. Fixed incorrect effects playing from item copies. Dropped items can no longer be shared.
Allows for easier customizing of whether or not an item should be shared with players upon pickup in co-op (e.g. it allows it to be expanded to weapons with custom cvars).
Localized functionality to an inventory function so that any item can make use of sharing. Added flag to avoid infinite recursions. HandlePickup() will now also share keys (for more complete handling). PuzzleItems are now included in sharing.
Adds CanReceive() to Actor, called by items from CallTryPickup(). This will let actors themselves determine if they can receive the item before any other checks.

There were two booleans that could be merged into the flag word.
This also fixes a bug with CHAN_NOSTOP not working for local sounds because it checked the wrong sound source for the playing sound.
