altboot:

- New funcitions: init_rootfs, mount_sd, mount_cf and mount_home for smaller code and easier debugging / bugfixing. These functions can be used by all plugins.
- Do not try to mount /sys, /proc, /media/cf and /media/home when they are already mounted (mainly for testing purposes)
- Added plugin: install-tgz
  This plugin allows installation of an OE generated .tar.gz rootfs onto CF or SD as a real filesystem or into a loopfile of user-defined size. Still needs some work but is usable.
