Title : Resistance
----------------------------------------
This is a pretty broad change and one I will trial to see how we feel about
it. Basically I have changed all skill resistances to be based on a
percentage rather than a fixed value. So for example:

Current:
Cast Blast: 250 skill level
Monster Resistance: 200
Damage = 250 - (random 0 - 100) - Resistance / 2
Damage = 50 - 150

New
Cast Blast: 250 skill level
Monster Resistance: 200
Damage = 250 - (random 0 - 100) * (250 / (250 + Resistance))
Damage = 83 - 138

So this reduces randomness slightly. This smoothing will become ore
noticable if you attack something much larger than yourself:

Cast Blast: 200 skill level
Monster Resistance: 400
Damage = 200 - (random 0 - 100) - Resistance / 2
Damage = -100 - 0 (always fail)

New
Cast Blast: 200 skill level
Monster Resistance: 400
Damage = 200 - (random 0 - 100) * (200 / (200 + Resistance))
Damage = 33 - 66 (not great - but at least its something)

Some skills are _meant_ to fail (like charm) - so if you find yourself
able to charm lvl 50 mobs, please bug it to me.

Feedback welcome!
