pfSense

Add some code to allow images to be seen when viewing current page

Note that images are broken from view current page. In order to see the images you really need to test with a captive portal client.

We do not allow captive portal to be run on bridges. Much confusion will and silly bug reports are not welcome any longer.

todo: figure out the new mystery which is our system in -HEAD. it sure is
shiny.

Actually check that the file exists before returning to avoid this error:

Warning: file(/var/db/dhclient.leases): failed to open stream: No such file or directory in /usr/local/www/services_dhcp_relay.php on line 35

Move ending </body> and </html> down to end.
