autofoo cleanup, put version detection in configure.ac

- Autogenerated files do not belong to the repository, remove those files.

- The version is also determined when generating the configure file, so remove
  the version.sh file as well.

- Remove ACLOCAL_AMFLAGS and the related entry in configure.ac to get rid of
  configuration errors.

- Do not create NEWS or INSTALL by using a lower strictness.

- Ignore autogenerated autojunk.
