Rough fixes and tuning for Apache 2.4

- Bumped package revision number
- Eliminated code referring directly to apache22 or apache24
- Added a switch to generate apache22 or apache24 format based on directories
- Renamed every reference to apache22, to apache24
- Prepped a module list that works with apache24
- Kept things running with a worker MPM setting
- Added a require_once to "service-utils.inc" for write_rcfile
- Fixed a few XMLRPC sync log messages
- Added some logging for config regeneration
- Fixed indentation for the security groups code
- Moved the <Proxy> definitions within <VirtualHosts> (works, but crude)
  This is how it must be done on Apache 2.4 or you get SHM/mutex errors.
