Chrome filesystem usage fix

[lharriscal]

Added code to clear google chrome cache and config upon xsession cleanup (ie user logging out).

This should fix an issue with chrome cache and config taking up too much space to the point of crashing the desktops.

Does remove persistance of config between user sessions, but it is chrome specific, and we do not explicitly support such persistance anyways.

Tested on my laptop with lightdm and works. Tested on OCF desktop by trinity. ``
