586609bb2c Remove ancient code to import keys from ancient plugins
There were a couple specific DRM removal plugins before the DeDRM plugin
was created. These are obsolete since a long time, there's no need to
still have the code to import their config.

If people are still using these ancient plugins, they'll have to update
to an older version of DeDRM first, and then update to the current one.

afa4ac5716 Starting on Version 7.0 using the work done by others. Completely untested. I will be testing things, but I thought I'd get this base version up for others to give pull requests.
THIS IS ON THE MASTER BRANCH. The Master branch will be Python 3.0 from now on. While Python 2.7 support will not be deliberately broken, all efforts should now focus on Python 3.0 compatibility.

I can see a lot of work has been done. There's more to do. I've bumped the version number of everything I came across to the next major number for Python 3.0 compatibility indication.

Thanks everyone. I hope to update here at least once a week until we have a stable 7.0 release for calibre 5.0
