added waila support for Deep Tank

I forked the waila mod integration for TConstruct to add it for our Deep Tank.

It hasn't been tested (so please check and re-check it :p) as I still need to configure my IDE to build a working version of this mod

PS: sorry for the huge amount of commits but as I don't have access to GIT from work, I have to commit each file one at a time using github built-in editor
