improved testing support

worked on ways to provide a better test suite:
- added -T rsyslogd command line option, enables to specify a directory
  where to chroot() into on startup. This is NOT a security feature but
  introduced to support testing. Thus, -T does not make sure chroot()
  is used in a secure way. (may be removed later)
- added omstdout module for testing purposes. Spits out all messages to
  stdout - no config option, no other features
- modified $ModLoad statement so that for modules whom's name starts with
  a dot, no path is prepended (this enables relative-pathes and should
  not break any valid current config)
