feature wish: queue for recording shows

[niwi-hh]

Currently you can download several shows at once. This is a problem if you download (or watch) more streams than allowed by your subscription. E.g. I am only allowed to watch two streams at the same time. If I watch live TV and download two more shows, the second show will just show the information, that I am using more than two streams.

Why would I want to download more than one show at once anyway? The reason is, that it takes a lot of attention to download several shows one by one. I guess it would be a lot of work to check by ZTVH with every start of a stream how many other streams are already running. But maybe a "queue-function" could be implemented, that would automatically download all recordings one by one.
