Update for changes in npf in -current. Did some restructuring (as per one of the todo-points). Update Makefile to make gcc conditional, and make clang more picky about code quality (there's quite a bit more to do in the Makefile..). Added a function for getting npf stats. Added two more test-programs.
Code normalization. Copy'n'pasted tabs by mistake.
Add metatable to rule objects.
Merge pull request #1 from cypheratheist/master
