Improve Symlink Handling

[lorenzleutgeb]

Hi! Thanks for ghq, it's really helpful. I'd like to suggest how to make it even better! ✨

Sometimes I like to create symlinks, especially for very long project names:

~/ghq/github.com/companywithverylongname/projectawithverylongname
~/ghq/github.com/companywithverylongname/projectbwithverylongname
~/ghc/github.com/c   -> ~/ghq/github.com/companywithverylongname
~/ghq/github.com/c/a -> ~/ghq/github.com/companywithverylongname/projectawithverylongname
~/ghq/github.com/c/b -> ~/ghq/github.com/companywithverylongname/projectbwithverylongname

These repositories are listed multiple times:

$ ghq list
github.com/companywithverylongname/a
github.com/companywithverylongname/b
github.com/companywithverylongname/projectawithverylongname
github.com/companywithverylongname/projectbwithverylongname

I'd like ghq to resolve symlinks, i.e. only list the "expanded form" in my use case.
