Remove command

[mirror-shades]

I have been using a prototype remove command to uninstall releases, it uses remove <version> and remove all to remove single packages and everything found in the hashstore. I am considering that there might actually be 2 ways people might want to remove all packages, one that only removes releases installed by anyzig, and one that removes all releases from the global cache regardless of where they originated.

I noticed something in the readme regarding need for a clean feature, is this the sort of thing in mind?

We could maybe do it the way zigup does it? Have a command that allows the user to mark which versions they'd like to "keep"? With this in mind we went with the verb "clean" meaning you're cleaning up the versions you don't need anymore but still keeping the ones you want.

Let me know what you think of the implementation here #47
