fix for issue #91 by making sure the base parameter could be ommited.
added support for {version} keywork supporting issue #92.
fix for parsePath when no keyworks found
added support for paths and names with keywords that shoud fix issue #92
use key instead of package name and support for {key} keyword (if needed).
if a path doesn't have variables use the 'old' method of concatenation.
changed README file to add version and key keywords.
