Homebrew updates notification

[Informatic]

Currently only way of seeing that some homebrew package has a pending update is going to its details panel. It'd be nice to either have a separate view with pending updates, or have some sort of overlay icon on browser list items when there's an update available.

With current repository schema it is not trivial to achieve, as package version is only exposed in package manifest, so we'd need to download package manifests of all installed apps separately from a repository.

Re: second part, it'll be important to have the version exposed as a field in the list of packages (repository) itself, otherwise it's difficult to have a practical update mechanism.

Since all manifest data is now exposed directly in the repository, this is much easier to implement now.
