Add a "lastest available release" information
Created by: galuel
Sakia should give the user information the latest available version on the software (it is yet done), and also on its official site sakia-wallet.org.
It is possible to do it in javascript like here : http://geconomicus.glibre.org/latestreleases.html
So people with version 1.7 will be aware it exists a version 1.9 for instance, and so he can update knowing the information.
