Continue update of TMT to 1.7.10

* __Updated dependencies__  
  You will need to download the files stated in the `build.gradle` file to the `./libs` folder

* __Re-enabled MFR and Forestry compatibility__  
  Now that there are public 1.7.10 releases of those mods

* __Use BuildCraft 6.0 API instead of 6.1__  
  The 6.1 branch is alpha and probably unstable, players would have 6.0.*
  But when the time comes, you can replace it with what it was before

* __Removed unused imports__

* More stuff like renaming variables, fix creative tab gear icon ...

The `BlockStack` API block ID methods are deprecated because modders should not touch block IDs any more and it's best to move away from it. For things like NBT, the block's full name should be stored rather than the ID, e.g. `minecraft:stone`, but this only should be done when everything is working fine.

Em nope that does not work. I tried that in 1.6.4. and it makes the textures of everything that uses that texture (Pressue Furnace) mess up thats why this here.
