Replace memory-chunk-store by zn-chunk-store

[rllola]

I have started to write zn-chunk-store and I have succesfully been able to store chunk in a ZeroNet user folder.
Can be usefull to replace the need of Webtorrent Desktop and always seed your videos when ZeroTube page is open.
Not 100% sure that it is possible but so far it is.

ToDo :

• Create get function
• Create destroy function
• Create zn-chunk-store repo
• Test

UPDATE : It doesn't play don't know why...

ZeroNet will have a proper torrent plugin in the future, hopefully with streaming support. Might be easier to use that plugin instead of WebTorrent. Standard torrents also already have plenty of seeders, so there won't be a problem with videos being unavailable. Just something to consider.

To use standard torrents could be a good possibility. I thought the javascript from this project could be adapted to ZT https://github.com/roeycohen/Bit-Player-Chrome-Extension but maybe I'm wrong. If you do it like that, when you close the ZeroTube page you stop seeding?

@obv-mikhail I have heard about that. That would be for sure a nice plugin to have. I still want to keep Webtorrent that could be use has proxy for other website to use to have access to the videos. This is maybe not a good idea.
