[Feature Request] Merging m3u and epg from all MAC's within a portal.

[AFrameWorker]

It would be neat if STB Proxy could grab the m3u and epg from every MAC address within each portal.

I find it quite annoying when STB Proxy starts moving things around, and my top MAC gets moved down, which means suddenly I'm not getting the channels from that MAC when I want to download the playlist.

Say, I have a MAC that has 20,000 results, but I also have another mac that only have 7,000 results. If things start to move around, and the MAC that contains 7,000 results only, then my playlist will.. only contain 7,000 result. I'd love if it could combine them and merge them instead.

Could imagine it taking a long time to load up the playlist editor with this though, so maybe allowing us to pick which MAC's should be prioritized for playlist grabbing, and the rest will be ignored.
