Export an application as a zip package, installable on another officity instance.

The zip contains a directory 'app' containing the app files (PHP scripts, XSL templates, CSS, Javascripts, images) and a install.xml file, containing the xSushee commands to execute to install the app.

If the app is already installed, the 'app' directory will be replaced and the install.xml file will be transformed to upgrade the existing objects and update the existing elements (elements are registered when installed with an application, so they can be later changed transparently).

The file is saved on the server and possess an accessible URL that can be later used with <IMPORT><APP> to install the app on another Officity.
