New Archery hooks

[lukep]

For the magebow addon, I would like to use hooks for:
(archery.lua)
- Projecting damage/effects (like Conduit or ranged_project)
- when every arrow is shot (eg, when ammo is used)
- A way to override/alter the hit calculations. I have one talent that gives a chance to hit any target (including high def and invisible)

Added Combat:archeryAcquire and combat:archeryHit
For the checkHit you can just superload
