net: enable connman service either

Stupid systemd will shadow connmand initscript with
connman.service but will not enable connman.service
when told to enable connmand initscript.  Sigh.
doc: better clean target

A bunch of intermediate files would be sitting around otherwise.
main, metadata: README update

There's not much sense in overduplication of documentation
(tends to get stale faster then), still it's not good to
just refer to the code as the PDF/HTML book is less useful
then; maybe drifting towards "recommended" bits with more
"advanced" things being impleentation-defined is better.
stage1: READMEdability fix

Kernel modules come as both *.ko and kernel-modules-*.rpm
and it wasn't clear enough whether to mention "ahci" or "v4l".
desktop+tde: drop obsolete cruft

These packages have been sitting there commented out
long enough to consider them for cleanup.
regular.mk: added mnt to regular-icewm

Thanks mithraen@ for creating a universal frontend script
for udisksctl/pmount/hmount user mount tools; let's try it
within the minimalistic GUI image for the starters.
