Plone.recipe.zope2instance

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

- Removed the test command support from the control script which lets us
remove quite a bit of hackery. Added a note about using ``bin/test`` instead.
[hannosch]

- Added an explicit `python-check-interval` option and change its default to
`1000` instead of Python's own default of `100`.
[hannosch]

- Changed default `zserver-threads` to two instead of four.
[hannosch]

- Changed client connection cache defaults. We specify a cache size of 10000
instead of 5000. Also changed ZEO client cache to 128MB instead of 30MB.
[hannosch]

- If we are used in an environment with Zope2 as an egg, we make sure to
install the mkzopeinstance and runzope scripts we depend on ourselves.
This is done even if they already exist, since the eggs may have changed.
[hannosch, davisagli]

- Added Zope2 egg to the list of dependencies of this recipe. This can cause
trouble for Zope versions before Zope 2.12 or Plone before 4.0.
[hannosch]

- Added the cache-prefix option for RelStorage.

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

- Expanded the RelStorage options, including keep-history and replica-conf.
[hathawsh]

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

- Added support for relative-paths in the script generation.
[jvloothuis]

- When `zope-conf` is set the config file will be directly loaded from that
location (it previously created a stub zope.conf which included it).
[jvloothuis]

- Added an option to avoid using the normal shell scripts for starting Zope.
This makes it possible to avoid the hard-coded paths in these scripts.
[jvloothuis]

- Allow the blob-dir parameter in RelStorage configurations.
[hathawsh]

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

- Support in line with fix for LP407916.
[gotcha]

- Changed the 'mkzopeinstance' call respect the 'bin-directory' option.
[esteele]

- Removed the `zope2-egg` option and the simple startup script from the recipe.
We assume that we have an egg distribution if `zope2-location` is not set.
[hannosch]

- Merged the `davisagli-eggified-zope` branch into the trunk.
[hannosch]

- Add a new icp-address option. This is useful for environments where
e.g. squid is used to front a Zope/ZEO cluster. See
http://www.zope.org/Members/htrd/icp/intro
[neaj]

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

- Add handling for RelStorage options.
[elro]

- Reinstall scripts on update which appears to be good recipe practice.
[stefan]

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

- Add a new zcml-additional option. This is useful for environments where
non-code configuration (such as database connection details for
ore.contentmirror) are managed through zcml.
