[Feature suggestion] In list of enabled repositories, add timestamp of their latest update

[bitbooster]

A simple suggestion: in the list of enabled repositories, for each repo, report to the right of the repo name also the last date said repo has been updated (although, I'm not entirely sure that it's an information that can be retrieved while checking for updates)

It could provide as an useful information for the user, to know if a repository seems to be essentially inactive or perhaps even abandoned.
