added compatibility module (passlib.utils.compat)

exports specialized range & map aliases, and some dict helpers

* all dict.iteritems() calls replaced with compat.iteritems(dict)
* all xrange() calls replaced with compat.irange()
* all range() calls replaced with compat.trange() and compat.lrange() as appropriate
* all map() calls replaced with compat.lmap()
