/usr/local/etc/rc is always the latest version.  Issue
popped up again since check_reload_status was replaced.

add actual memory/disc/swap usage in dashboard, feature request https://github.com/opnsense/core/issues/66

- remove the use for pfSctl, replaced with a new configd control script to be able to remove the check_reload_status port
- replace use of global $g['booting'] because some scripts use this outside the main loop which causes strange behavior ( for example dhcp client which starts a newwanip on connect ). replaced which check on file /var/run/booting which is set in rc script

- extra code injection prevention for script types
- add script_output type (return script results from stdout)

Also style, license prettify, obvious bugs along the way.
