Not yet attached to the gui

* Forms have been revamped (CSS + javascript),
* Process has been improved : errors are displayed on the form page,
* Some changes in the index.php page so that everything related to installation is in lib/setup.php
* Also added a small function in OC_HELPER class to set input values.

All these should improve the installation process in terms of ergonomics.
Well, I do hope so.
