[Feature request] Show last update or age

[Tekl]

It would be very helpful to identify outdated Apps directly in Applite. Thus, you could show the time since the last update and allow sorting by date.

You can view outdated apps in the "Updates" section. Some applications manage updates on their own and don't appear as outdated, but if you want to see the full list of outdated apps click "Show All Updates" in the toolbar.

The last update of age is not available through the Homebrew web API, so getting this information would be too difficult.
