www/htmldoc
www/htmldoc-x11
The latter is now just www/htmldoc built with a specific set of options.
Changes include:
+ Add options.mk that supports a new option:
htmldoc-gui Build with GUI support
+ Remove Makefile.common and move all logic into htmldoc/Makefile and
htmldoc/options.mk.
+ Add full DESTDIR support.
+ Bump the PKGREVISION for htmldoc and htmldoc-x11 to 7. Both packages
now track and use the same PKGREVISION number.
