1.6.* support added

No fixes for 1.5.* support yet. This update is not comprehensive, but supports RR 1.6.*.
Massive mod support extension and second ID pass

A major effort has been made to unify mod block/item IDs to get them to use specific ranges, and especially in the case of mods with addons the addon mods have had their IDs changed as best as possible to bring them closer to the ranges their parent mod uses.

This process was not totally successful, and TiCo and Forestry still have their bizarre ID range spread.

Ultimately this process makes it considerably simpler to both add extra mods to the game and to read the NEI block/item list in full in-game. Further development is strongly encouraged to stick to this practice.
Final mod support pass for the initial release

NO BALANCING WORK HAS BEEN DONE YET. THIS IS JUST A "GET IT ALL TO START A NEW WORLD" JOB AT THE MOMENT.

Mods that either don't work or don't have a 1.6.* release at all are of course missing at this time.

Metallurgy 3 only just fits in here, so let's hope it doesn't get much bigger!
Adding 1.6.* ID Maps

NEI has redesigned its ID Map dump system to output more types of registers, for example it now outputs biome data as well as blocks and items. Consequently the dumps now require a folder of their own instead of just one text file.
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.
Emergency patch to correctly implement HexWool support

tl;dr: I suddenly realised it wasn't installed correctly and quickly fixed it.
Cleanup and reorganisation for release of RU 2.0.0.0

Note that mIDas features have been suspended until further notice because what's the point when everyone's so intent on scrapping their own content all the time?
