Map device interface improvements

Every tablet slot should hold several (up to however many different types of tablets we have) tablets. You should be able to see them all when your cursor is over that slot and scroll through them with mouse roll to pick an active one.

Ability to TOGGLE tablet slots on/off (without taking tablets out), in case you don't wanna waste some or any tablets on a particular map.

Mini (or not so mini) inventory WITHIN map device to store and sort out tablets.

Or a way to access stash directly from map devce (having them both, map device and stash, opened on the screen at the same time).

Also get rid of "realm gate", "reliquary vault" and whatnot and bring this functionality to map device.
