Documentation edits

Edit the documentation for minor grammar, idiomatic usage, and sentence construction issues.  Overall the documentation is great;  this is just cleaning up some places that sound a little odd.

There are some notes left in the documentation delimited by [bwb: ...] where I made a larger-than-usual change or I thought needed attention from someone more familiar with the codebase than I am.

There’s also the confusion factor of what exactly is the difference between creating an authenticator and initializing an authenticator.

Never mind.  I just remembered about embedding it into a request.  I don’t think there’s an example of that in the seed application.
