doc updates, plus back-end work for rpost to let you post to a different channel than your current logged-in channel. Need the same for rbmark back-end. Then we "just" need a selector widget on the editor forms.
Update documentation on connecting to channels and on documentation.

Update documentation on connecting to channels and on documentation.
introduce a connection type called 'ifpending' for number 6 of issue #395 - so that we can still have an unconditional 'pending' link. Needs testing before integrating with the nav menu
finish "ifpending" connections
provide the ability for rpost to post as another of your channels. This does not yet work, so the functionality has not been enabled.
this makes rpost to another channel work somewhat - but there are issues, since the ACL will belong to the wrong channel. Leaving disabled for now. I don't know that we can solve all the issues without a different design so this may end up in a plugin for those who are willing to put up with the shortcomings.
