Another go at improving the screen dimming and suspending setup:
Lockscreen invocation after 5 minutes, dimming at 10, sleep after 15 -
but only when not on AC.
It tries to also fix the screen being stuck off by reordering the
timeout and resume options of swayidle.
New versions of Iosevka seem to not be callable simply through 'Iosevka'
as before but require the full 'Iosevka Nerd Font' terminus for my case
of having the archlinux nerdfont package for the font installed.
This commit fixes wrong fonts in wayland and the wezterm terminal as
well as a longer running issue in mpv so they all correctly display
Iosevka.
Since the existing wayland module basically describes everything about
my 'desktop environment' setup already anyway, might as well rename it
accordingly. Additionally, mako is important for notifications in this
environment so it moves here as well.
