Merge pull request #2 from kirbyfan64/master

Added globbing support
added kirbyfan64 as contributor
fixed two errors (globbing and normpath)

the globbing error was a result of the glob.glob call returning nothing
minor enhancements
fixed bug and added clean_path that does rel paths

the bug was pointed out by kirbyfan64: not all the paths (outputs
and dependencies) would be normalized before check_for_deps_in_outputs
was called and it caused improper building of the edges of the
dependency graph.
