desktop+lxqt+razorqt+extra: added qpdfview stub

Neither qupzilla nor pcmanfm-qt will fire this up
automatically when dealing with a PDF file so rather
adding a reminder to have a look at it some day.
rescue+extra: added lnav

A cute little utility that can come handy
while inspecting a failed/broken system.
added docs-publish toplevel goal

This one is long overdue as I keep forgetting to update
the published copy of generated documentation all the time.

Note that you must pass DOCS_PUBLISH (as a local directory
or host:dir suitable for rsync/ssh) via make arguments,
environment or ~/.mkimage/profiles.mk file.
README: explained wiki link

Some seem to be skipping it over for no good reason
while even unfinished HOWTO is much beta than nothin'.
live: s/fonts-ttf-droid/fonts-otf-mozilla-fira/

fonts-ttf-droid have been superseded by fonts-ttf-google-droid-sans
in Sisyphus which might be lacking; I've considered replacing it
with Fira anyways, so let's just do that.
live: disable livecd-evms

Looks like sysvinit-only services like this pose a major problem
for systemd-214 causing dependency cycles.
x11-autostart: ensure prefdm startup

systemd-214 has broke things badly enough so that
graphical boot target is not effective anymore;
enabling prefdm explicitly helps though.
regular.mk: tweak desktop services

systemd-214 has major problems with starting these services,
and KDC should definitely not even try to start up before
setup (which is not feasible given that these are LiveCDs).

domain-client pkglist inhabitants and net-usershares feature
are nasty enough to bring a lot of extra garbage in unfortunately
(alterator-auth, alterator-kdc, alterator-net-shares involved).
