Work on issue #25

Implemented Thaumcraft API to make our block/items give off aspects. Not
sure what aspects they should give so I just took arbitary values and
assigned them. Mod works with/without Thaumcraft. But needs Thaumcraft
API to build if implemented. Won't change readme.md until we decide and
implement into master.
Final work on #25 before merging to master

Updated instructions in README and tweaked amount of aspects you recive
from different items in our mod.
Merge remote-tracking branch 'origin/thaumcraft'
