Replacement library: embedly2

[JelleZijlstra]

Unfortunately this library appears to have been abandoned. I just released embedly2 0.6.0 (https://pypi.org/project/embedly2/), a fork of this library that drops Python 2 support and fixes #31. Feel free to use it and report bugs if you need to use embedly with a recent toolchain.

If the original maintainers return to this project, I'm happy to archive my fork in favor of this package. Also, if anyone would like to contribute to improving embedly2, please let me know.
