Update package dependencies that are using Github in stack.yaml
This is still work in progress but usable (not perfect but usable)
Build from source for now
Update specific repo
$ stack-updater update <reponame>
or choose repo interactively
$ stack-updater update
<reponame>
must be in full form owner/repo
like shulhi/stack-updater
- Only works for git repo hosted on Github
- No support for mercurial
