Implement AMMO- component about boom HOT 2 CLOSED

Should probably not have a new ammo-component, and I started implementing an inventory-component.

But changing the weaponactioncomponent to a inventory-component that has an or separate object(s) with ITEMS, WEAPONS, AND AMMUNITION and then an ACTIVE WEAPON and ACTIVE AMMUNITION - this could keep track of everything for the given entity.

Since it already triggers the shooting from input its easy to reduce ACTIVE ammo after a successfull shot is made, its easy to change weapon and ammo - as long as every weapon has a basic shoot function with a true/false return if it actually fired!

This also makes it possible to send an updateHUD signal when the ammo, weapon changes or reduces etc... (As well as a list of available ammo, weapons...)

from boom.

Will wait a bit with clip size and reload until i feel the ammo/inventory works - but should not be hard to implement in current scheme

from boom.
