Customizations in Qgis Web Client

Hi,

I written some code to add the possibility to customize the qgis web client by adding more buttons to the toolbar.

To test it:

 - rename site/js/Customizations.js.templ to Customizations.js;
 - uncomment all lines;

This would be great in QWC, since that it will be much easier to update the QWC code with future "git pulls"!
