I've fixed the various scripts etc. in the CVS so that I can now install a ZEO client/server setup. The way it actually ended up working is:

- runzope.py and zopectl.py are moved to Zope/Startup/run.py and Zope/zdaemon/zopectl.py respectively
- bin/mkzopeinstance now takes a "-z/--zeo host:port" which sets up a custom_zodb.py in the new zope instance home
- bin/mkzeoinstance now overrides less, because...
- ZEO/mkzeoinst.py generates an additional script, runzeo, which is the "runner" for the ZEO server. Both it an the zeoctl script need to know about the ZOPE_HOME, so that's been added to the scripts (via the params)
- fixed setup.py so it installed ZEO/schema.xml
