Plone.recipe.zope2instance

---

- Small documentation update. Added link to the bugtracker.
[hannosch]

- Changed default of zope.conf option 'default-zpublisher-encoding' to 'utf-8'
instead of Zope's default value of 'iso-8859-15'.

- Have PID file's location default to '${buildout:directory}/var/${name}.pid'.
Keeping the PID file in $INSTANCE_HOME gives trouble when buildout rebuilds
the part.

- Increased 'zodb_cache_size' default value to 5000, which is more likely a
better default these days.
[hannosch]

- Added support for 'extra-paths' as in 'zc.recipe.egg'; this is useful when
using regular python packages for which no eggs are available (yet), i.e.
with 'plone.recipe.distros'.
[witsch]

- Added zeo-storage option (merge branch ree-add-zeo-storage-option).
[ree]

- Avoid doubled entries to eggs specified in the buildout in 'sys.path':
the working set ('ws') gets passed again when installing the script
('bin/instance'), but it is not also added to 'extra_paths'.
[witsch]

- Patching 'PYTHONPATH' in the Zope startup skripts should insert all
additional paths (to eggs) __before__ 'SOFTWARE_HOME', because otherwise
(newer) egg versions of components from the standard Zope distribution
(i.e. stuff that lives in 'lib/python') cannot be used.

- Changed the option to suppress deprecation warnings to "--nowarn" or
'--nowarning" to be consistent with "zopectl test".
[witsch]

- Added option "-w" to allow the test runner to suppress deprecation warnings,
so it's easier to spot failing tests...
[witsch]

- Updated import for Zope 2.7 (and below) compatibility.
[duffyd]

- Merging -r51966:52659 claytron-zopeconfoptions branch to trunk.
[claytron]

- Made the config snippet prettier while still getting the resulting
indentation right.
[witsch]

---

- Added support for zodb 3.8's "<blobstorage>" directive.
[witsch]

- Added a script name arg before callint zope.testing.testrunner.run.
zope.testing.testrunner:1772, get_options removes the first arg from
the list of arguments expecting a script name there. Was causing
"bin/instance test" to behave improperly.

- Use bin if present falling back to utilities. This makes it possible to use
a Zope version installed from a tarball and not compiled inplace.

---

- Found the problem with strange environment variables.
[hannosch]

- Fixed documentation bug, the cache size is respected by non-zeo instance as
well.
[hannosch]

---

- J1m actually read the docs ;)
[hannosch]

- Attempt to fix the sometimes insane number of tests which are found by the
test runner.
