NOTIMPL, or... impl by using the passed in properties and permissions.

I am not quite sure why this wasn't implemented in the first place. I plan on
investigating it and then implementing these. Till then, the code for properties
and permissions gets called from all over the place. I don't want to break
things by putting in NOTIMPLEMENTED everywhere.

Instead of putting TODOs in every single place where properties and permissions
are being used, I've created a bug to track this work.

[scheib, 2016/04/27 05:12:59]

The local objects aren't created anywhere yet though, are they? I'm not clear on
how these are being called.

[rkc, 2016/04/27 19:41:06]

You're right. This can be marked NOTIMPLEMENTED. I was confusing this with some
of the code on remote which does get called.
Done.
