#5 Add console to interact with hylafax

[Pierangelo Repetti]

Add an interface towards HylaFax commands and queues to the administration panel. This might be very useful when:
- you don't know where your fax is hiding
- you wrongly added 101 copies of the same fax to the sending queue and you would like not to send them all
- you'd like to reset and clean every queue
- ...other similar situations.

Browsing through hylafax man pages could be too time consuming and not rewarding.

This "hylafax" console should interface not all hylafax commands but only those relevant to the Communications Suite:
- manage sending queue (eg. browse, empty, cancel a single fax)
- manage fax devices

Thanks
