images, for images with different illuminants.

DelphiWorld found another typo. Also remove the condition for auth since all dialplan lookups should be authed to prevent fraud.

Adding a new configurable radius module that will support both authentication based on a dialplan app, as well as digest based radius authentication by hooking into the directory. It is also fully configurable on which fields to send by the config file.

Colour and grey images can down be dithered down to bi-level images for transmission as faxes.
More movement towards T.42 support
