Plone.recipe.zope2instance

------------------

- Fixed error introduced in 4.1.1.
[hannosch]

------------------

- Disambiguate the `blob-storage` option if `shared-blob` isn't used. In this
case we use `var/blobcache` as a default location, so we don't accidentally
overwrite the real blob data with a blob zeocache. Refs
https://bugs.launchpad.net/bugs/645904.

----------------

- Give the `readme` an overhaul, group options into sections and mention the
most commonly used ones at the top.
[hannosch]

- Add some flexibility to `site.zcml` creation. Thanks to Wolfgang Schnerring
for the patch. This closes
https://bugs.launchpad.net/collective.buildout/+bug/335311.

- Raise an exception if both ZEO and RelStorage are configured at the same
time. This closes https://bugs.launchpad.net/collective.buildout/+bug/645100.

- Added support for zc.buildout 1.5, while retaining support for 1.4. Thanks
to Jeff Rush for the patch. This closes
https://bugs.launchpad.net/collective.buildout/+bug/683584.
[hannosch]

------------------

- Added support for specifying the new RelStorage options shared-blob-dir,
blob-cache-size, blob-cache-size-check, and blob-chunk-size.

------------------

- Add friendly error message if non-admin tries
"instance install|start|restart|stop|remove".

- Exit with the return code of the executed do_* method. This closes 10906
(clicking "Restart" in ZMI control panel caused shutdown).
[kleist]

- Implemented the "restart" command for "bin/instance.exe".

------------------

- Setuptools / Subversion ignores empty directories and doesn't include them
into the source distribution. Added readme files to the `bin` and `var`
directories inside the skeleton. This lets persistent ZEO caches work again,
which want to put their files into the `var` directory.
