updated theme adben

The theme "adben" was updated:

The theme now provides two customizable header functionalities : 
a) displaying a pseudo-random message from a database of quotations
 (https://en.wikipedia.org/wiki/Fortune_%28Unix%29)
b) displaying randomly command line tips from The command line fu 
 (http://www.commandlinefu.com) community.
This theme provides as well information for the current user's context, like;
branch and status for the current version control system (git and svn currently supported) and time, presented to the user in a non invasive volatile way.

More information in the Readme of the theme,

Thank you,
