Update include() to include_once()

For safety, use include_once() when including various "side" files.
There are a couple of instances of include("guiconfig,inc") that I
changes to use require_once() to be consistent with everywhere else.
The remaining cases of include() are just (hundreds of) head.inc and
footer.inc - those are only at the start/end of the ordinary top-level
interactive PHP files. There is no nested interaction of those to think
about, so that should be fine.
