Feature Request: support for wildcards in links

[craigjmidwinter]

It would be nice to see support for wildcards in paths for links. The usecase being, if I've got a ~/scripts directory that I want to track with some common scripts, and I want to run it on a system that already has a ~/scripts folder, instead of having ['scripts'] in my configuration and clobbering the path with the link, i would be able to have ['scripts/*'] and create links for all the files in the scripts folder from the HM_SRC
