dockerdev improvements

I'm now on version 0.9.0 and realize that it uses long cidfiles, so I
fixed the dockerdev scripts to handle that.

Use "--cidfile" instead of "-cidfile" on newer versions.

Made the version module handle determining what behavior we need to
change instead of just calculating the version number.  This makes the
other modules more readable and also makes it a bit easier to change
things.

Added migration/management command to lookup youtube channel ids

We want to migrate to the new externalsites code in the gh-1488
branch, however to do that we need to have youtube channel_ids instead
of usernames.  This branch can be used to generate those in
preparation of the migration.
