Fixing codestyle

issue #6167

issue #6122

issue #6122

issue #6114

register_globals was removed in PHP 5.4, and zend.ze1_compatibility_mode
 was removed in PHP 5.3, so it makes no sense checking for their value in
 the setup.

This replaces save_object and execute methods by 3 methods:
readPost - Reads POST data
update - Update object state
render - Render HTML UI

The point is to avoid reading POST and rendering HTML when this is not
 needed (when doing stuff through the webservice for instance).

It’s also more consisent across FD with all classes handling some kind
 of dialog implementing the new interface FusionDirectoryDialog which
 makes sure these 3 methods are implemented.

issue #6072

Bumped minimum PHP version to 7.0.0 because we use strict typing.
Removed fallback for random_int.
