Silence foreach() error when no PPP interfaces exist

Setting the VIP to the VHID ID has to be the
single most brain-headed decision in the history
of man-kind. Do this correctly by finding the first
available vip interface.

Unbreak find_interface_ip for normal interfaces

Unbreak CARP Enable/Disable button

Unbreak status -> interfaces. TODO: Unbreak Disable Carp button

Unbreak find_interface_ip(). test case: echo find_interface_ip(lan);

Correctly fix the function so that the table expands again.
Whoever rewrote this must have been sleep deprived or really lost.

Unbreak filter_get_direct_networks()
Check if the array is empty

Remove double dollar sign

Restore the filter_get_vpns_list() functionality
Increase readability
