Revamp of touch attack damage calculations

Goal: Make touch attacks equally effective as weapons for built characters while significantly lowering their usefulness for 30HP PKs.

Here is how damage is calculated:
1) Damage = Base Damage (4 to 9 for ToF - on par with a spirit hammer)

2) Damage = Damage scaled by skill (not SP!) from 0% to 100%
This means that you no longer have to worry about SP, only about your percent in the spell, when casting your touch attack. This brings touch attacks in line with weapons.

3) Damage = Damage +5, depending on the casters HPs.
Touch attacks are way faster to level than weapon proficiencies. As a result, proficiency damage is based on the casters HPs instead, gaining 1 bonus damage at 60, 2 at 70 and 5 at 100 HPs.

4) Damage = Damage * Mysticism bonus (works the same as might bonus)

This basically brings touch attacks in line with weapons, allowing them the same damage range and late game use, but curbing their early game PKing potential (together with a change to JoF).
Implemented JoF into touch spells.

Each JoF gives 1 extra damage at 60HPs, 2 extra damage at 80 HPs and 3 extra damage at 100 HPs. This puts a ToF with one JoF on par with an attack made by a scimitar. The JoF itself grants the same -20 to SP.
Duration is increased greatly and based on skill percent.

The last addition to make touchattacks equivalent to weapons. The duration of the spell is greatly increased, and just like weapons, you don't have to worry about what gear you wear when you put them on.
Added procs to touch attacks.

Touch attacks now have a up to a 5% chance to proc an effect, this chance is increased by 5% for each JoF equipped and scales with HPs, from a 0 chance at 50HPs to the maximum value at 100 HPs. The individual proc chances can be set in the properties section.

The procs and chances are currently the same as weapon procs, except for holy touch and acid touch.

Zap - Purge
Touch of Flame - Blind
Icy Touch - Hold
Acid Touch - Dusk Rat Poison without Vertigo effect
Holy Touch - Heal for the amount of damage dealt by the attack
