Feature request: notify user of updates to installed packages

[David Reitter]

Feature request from a user:

Can we automatically show a note (in the echo area) to notify the user when a 
Packages (ELPA/MELPA etc) package is installed, but a newer version is 
available?  Can they then be semi-automatically updated?
