In-place documentation (rebased onto develop)



This is the same as gh-713 but rebased onto develop.

----

Along with the in-place CLI options in `5.0.0`, we are now releasing the documentation for in-place import with `5.0.1`. This takes the `InPlace.pdf` and the `ImportScenarios.pdf` from http://ci.openmicroscopy.org/job/OME-internal-merge-docs and makes them part of the standard sysadmin documentation.

Note: the command-line options are still not overly visible since it would be difficult (at best) to get someone to leave the CLI and read the documentation which has numerous caveats.
