This partially reverts commit c57aefd48b10ca3cabc9df162bc32efa62a6a21e.
The code to check against hashed tokens remains, because existing tokens
should still work.
The unhashed tokens are necessary for fetching badges from Blender ID.
These changes mostly revolve around the change in ObjectId constructor
when running on Python 3.6. Where on 2.7 the constructor would accept
12- and 24-byte strings, now only 12-byte bytes and 24-character strings
are accepted. Good thing, but required some changes in our code.
Other changes include hashing of strings, which isn't supported, so they
are converted to bytes first, and sometimes converted back afterwards.
Refactor of pillar-server and pillar-web into a single python package. This
simplifies the overall architecture of pillar applications.
Special thanks @sybren and @venomgfx
