Some minor fixes

Loosened up alt-tab checks and fixed a bad return for accounts callback.
Added distance check to vehicle interaction

Somewhere along the line, vehicles aren't being removed from player
near-lists resulting in players accessing trunks from far away. This
prevents that but the source of the issue is still unknown.
Updated tutorial, fixed some virtual world issues

Added OnPlayerWearBag and OnPlayerRemoveBag events to Backpack module.

Fixed virtual world item drops when dying in a different virtual world.
Also fixed virtual world and interior setting for unloaded weapon
ammunition.

Tutorial is half done (items, inventory and weapons). All that's left to
write is the vehicle and construction elements.
