make RepoUpdater's index URL a property for easy use

Browse Source 
Since the DownloaderService's events are all based on the complete download
URLs, and RepoUpdater is where the update URLs are built, this makes the
full download URL into a read-only property of RepoUpdater so it can be
used wherever there is an instance of RepoUpdater

This is also important because having the `final` property highlights
the lifecycle of that variable: it does not change during the entire
life of a RepoUpdater Instance.
