Started work on Ex Nihilo addon
Generalized Exnihilo related code to support other kinds of recipes
Added sieve recipes
Added more output slots
Fixed tool permutations not showing, fixed NEIPlugins registration, fixed not all hammers being found
Updated mcmod.info and added exnihilo module to it
Added WAILA plugin for Ex Nihilo
Reworked Hammer/Sieve recipe display logic, rewrote some of it in scala (because screw java)
getRecipeId can't be val - accessed from superclass ctor
cleanup
Update readme.md
Ported ex-nihilo stuff to 1.7.2
Removed WAILA handlers that are now part of Ex Nihilo itself
