Made Thaumcraft 4 a direct download from the internal repo

His new blanket perms (with caveat) and the release of Thaumcraft 4.1 made this necessary to do now.
Licence corrections

JourneyMap doesn't like you hotlinking directly to the adf.ly anymore (really?) so I've moved the browser link to their preferred location as a courtesy.

We have Chococraft perms again and I never actually corrected that, so here we go.
Reorganize dependencies to match new ATLauncher guidelines

(I only got alerted to this because Trunks had trouble getting Lite authorised because of this change.)

On the plus side, separating the dependencies as much as possible will make it easier to update FMP in future.
Standard config compatibility update pass
New mod configs and an obscure ID conflict fix

That one didn't get caught for ages, this might cause some minor damage for Extra Cells users.
BD2 spawn rate changes

The consensus is that BD2 is too "OP", although people have trouble placing exactly why and it's subjective, like everything.

What did become clear is that the spawn rate of the dungeons is currently too frequent... or rather it's either too rare or way too frequent, averaging out to merely "OK".

This set of changes aims to fix the weird clustering behaviour we're seeing. If in the process dungeons become too rare we will accomodate that accordingly.

Additionally, as a bug fix attempt, the loot added directly by BD2 is disabled (most of it being grossly underpowered in the pack anyway).
Community-suggested fix for bizarre NEI behaviour
RR 2.6.15.0-EXP XML update
UE 3.1 incompatibility rollback hotfix

A couple of our mods have not updated to UE 3.1 yet, and any attempt to load a world with these UE 3.0 mods caused painful crash issues.

The entire UE suite has been rolled back to the last UE 3.0 builds until everyone gets with the program, as the 3.1 bugfix is actually quite significant and worth the upgrade.
