Add support for ondemand.mtv.it (was: New Request)

[marste]

It's possible to download from http://ondemand.mtv.it/ ?
With the latest versions is no longer available to download from PornHD.
Thanks!

Please don't post multiple requests in the same issue, the second site has already been requested in #2270. We will use this issue only for the mtv support.

Sorry, but the issue #2270 was written after mine...

[jaimeMF]

Sorry I didn't read the time of creation, anyway, we'll use this issue for mtv and the other for pornhd (you can subscribe to get the updates).

Thanks! :)
