Reactivated the "fresh install" code in the Bootscript, but modified it

a bit:
* Added directory /etc/post_install, which can contain scripts that will
  be executed on the first boot.
* Moved the mimeset invocations to such a script. Use the "-apps"
  option instead of "-all". Since create_app_meta_mime() (and thus
  mimeset) work recursively now, running the commands does actually have
  an effect.
