Merge lighttpd configuration into one include file.

The lighttpd configuration was previously spread across several files
which were intended to overwrite the defaults.  They often became
outdated.

Now all customization is in lighttpd/rlgallery.conf, which should be
included at the end of whatever main lighttpd configuration file is in
use.  It should require minimal updates for new lighttpd versions or
distribution changes.
