Check if c is fullscreen before reparenting it to LyrFloating

Closes: https://github.com/djpohly/dwl/issues/487

make sure that fullscreen clients are on the correct screen when isfloating is true

Bug: https://github.com/djpohly/dwl/issues/487

include dwl.desktop in the tarbal

allow specify DATADIR (to install desktop file)

Add desktop entry file

fix typo

call setfloating in setmon

since in the previous commit we may not applying floating in clients
this is to make sure we do

return early if the client doesn't have monitor in setfloating

there is still a bug, but for now this prevents a segfault

prefer IRC over Discord

I regularly check the discord server, but it is much more likely that I will be
online on IRC, and djpohly does not seem to be active on either.

just add define

tagcount should have been a #define

return nothing in xytonode()

we do not use the node

Style: use early-return to clarify code

Use an early return to avoid indenting the main logic instead of
wrapping the tail of a function in an if statement.

No functional change, except for a handful of places where printstatus()
was being called spuriously (tag, toggletag, toggleview).

No need to send surface.leave/enter events

The scene graph implementation sends these for us, and it does so more
accurately than our overly-simplified approach.  Layer shell surfaces
don't appear to receive these events at all, according to my
WAYLAND_DEBUG experiments with bemenu and dtao.
