issue #6072

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.

Use a thrown error instead of calling msg_dialog and exit.
And use an exception handler to format uncaught fatal errors.

msgPool always returns escaped string because it may be used from
 smarty.
htmlescape now calls htmlspecialchars instead of htmlentities, allowing
 to escape strings with % without losing sprintf capability.

issue #6071

This cleanup solves some more escaping problems

issue #6071

Adds FusionDirectoryError base class and one child class for check
 failures.
Use this new class for IntAttribute as first test.

 crash happenning in index.php when using encrypted password in config
 file.

The code tries to support generators from modifiers so that random

 large arrays in memory.
