[AD] Config routines, alpha 5

["Angelo Mottola" <a.mottola@xxxxxxxxxx>]

Another alpha for your pleasure :)

Changes:

- The write hook is now effectively called *after* the variable has been
set to its new value.
- All al_set_* and al_get_* functions now accept variable arguments; I
was also forced to change their syntax in order to support this, so now
you have:

al_set_bool(value, key, ...);

al_get_bool(default_value_on_errors, key, ...);

- Added al_get_type returning the type of given entry
(ENTRY_TYPE_UNKNOWN on error).
- Added al_enum_config_keys, returning a list of key names matching
specified path.
- The code is now a bit more commented.

ToDo:

- al_load_config/al_save_config: I'm still waiting for this so we can
better discuss about related issues.
- more al_set_*/al_get_* functions: al_set/get_args come to mind.
- unicode support. UTF8 by default?
- ?
