Some doc fixes. Correct mod_python.so location. Add SYSCONFDIR to
options in version.py. Add MaxConnectionsPerChild. Add a
write_basic_config() function which can generate a stock Apache config
for a (currently just wsgi) app. Add a few command line params to
mod_python command for config generation. Make "mod_python version"
output a little better. Change quoteIfSpace to quote_if_space and
move it to httpdconf.
