Crude Fix for #123(Issue) (Silent Gear Arrow Still takes Demage)

[linuxchr]

This is a crude fix for #123
This does not fix that problem directly, it only elivaties the symptoms porblem somewhat.
It works by enableing repairing with a material directly, so that the arrow etleast can be repaired.
It also add incredible efficiency for repeairing directly.
It adds a tooltip telling the player that arrows are not unbreable.
It removes the item from item_durability.zs as this adds the word unbreakeble in the tooltip which could lead to confusion as the item isnt acutally unbreakeble.
A better fix is not possible as silentgear has no option to disable ammo consumption.

Reworked this in a different direction and removed the Arrows completely as I'm unsure of the extent of issues trying to keep in the pack: 4280d6e
