Add new 'registry' command that just open http://code.dlang.org

A way to solve #663

I think the command line tool should provide the expected dub search functionality.
Adding a dedicated command just to browse an URL isn't justified IMO.

How would a dub search command be better than opening an URL?

Probably mostly for command-line fanatics, but since the core functionality is already there, it's an easy target. An advantage apart from working without a GUI is that the search output can be processed by a shell script to do additional things with it. Of course using the website has a lot advantages, too, and something like dub search -web could be an alternative if there is demand.

Well, I use DUB day in day out. Opening http://code.dlang.org is a common task.
dub search -web would be ok of course.

I added the dub search command, so it would be easy now to make dub search -web 'foo bar' open http://code.dlang.org/search?q=foo%20bar.
