Support resolving the latest sub-revision of a module 

Components of revisions are separated by dots or hyphens.

In case you "end the revision with a `+`" (see [1]), the latest sub-revision of the
dependency module should be selected when resolving dependencies.

Accept revisions such as "1.2+" or "1.2.+" and "1.2.3-+".

Fixes #424.
