So we really weren't deferring the loading of client libs dadgummit,
do that for real where possible. This shaves a couple of tenths off
the static import times.
Also defer as much import-time procesing as possible. This is a little
ugly in api.auth but this also eliminates import of the auth plugins
until they are needed.
