pfSense

Clean backup cache before starting php environment

Keep 5 backups on embedded. Keep 30 on full installations.

Add multiline support for multi-line mini programs/scripts.

Show that exit is a valid command

Add pfSense php shell option. This will be used by developers to tell operators how to remove blank config options and many other things that will be easier than instructing someone to edit config.xml directly, etc.

Escape $ so that it does not try to print out the variable

Add a pfSense interactive php shell for developers.

$config needs to be a global. Someone needs a pointy-hat!

Change Miniupnp to UPNP

Use $_SERVER['argvc'] and $_SERVER['argv'][$x]. This fixes the linkup issues (hotplug)
