Update Health/Mana Affix methodology

[Surfpup]

In the interest of improving compatibility with other mods, and as well in the interest of making it not-so-impossible to upgrade your health/mana, I'm thinking of utilizing the crystals as usual, and maybe making some health/mana affix bonuses work based on a percentage of your actual stat.

This will reduce confusion and simplify the balancing act by giving everyone the same experience instead of splitting it into two versions.

There may still be affixes that add to mana and health outright, but the values should be greatly reduced.

Will still need to consider balance of the mod. Now that health and mana are back to being relatively easy to obtain, the mod doesn't have much negative affects on the player and affixes generally make things easier.. so overall, it's leaning towards making it an easier game. This is not a good thing.

I could definitely think about working on the NPC affixes some more. More powerful enemies might help make it more challenging.

I'm also thinking about making the player character have 'perks' which are essentially affixes that are permanent on the char. But, you would be required to choose from negative ones as well. This might be handled in a separate add-on mod... Then again, if it's for real balancing purposes (and of course, adding variation to the gameplay), it might be a great fit for this mod, and I'll just have to make sure I create a 'core' version of the mod for those who only want affixes and nothing else.
