Balance pass

This is meant to closely resemble, but not match completely, RR 1.5.*. These changes should make the pack suitable for wider testing.

Ore worldgen is primarily handled by Metallurgy, including vanilla worldgen. The settings are preliminary and subject to change based on player feedback. The following mods also have select ore worldgen enabled:

Applied Energistics: Certus Quartz
Artifice: All
Atomic Science: Uranium
DartCraft: Force Gems
Emasher Resource: All except tin/copper
IndustrialCraft2: Lead, Rubber Trees
Mekanism: Osmium
Tinker's Construct: Aluminum, all Oreberries

The more exotic/esoteric the Metallurgy worldgen, the rarer and/or more obnoxious the y-ranges it has been placed in. ;)

This update also removes files added by mistake, such as obsolete mod configs and personal TabbyChat settings not applicable to this release.
