New better swaywm 1.6 packages and slackbuilds

Find them at https://github.com/biker-rat/new-bet...s-and-packages
This time I used the Alienbob slackbuild toolkit to generate all the slackbuilds and all of the tweaks are in patches. Please try them out and comment constructively here. It would be great if Pat could include sway in testing for 15 (or else current) or even if alienbob could add them to his repo.
The scdoc patch addresses an issue I had with sway finding scdoc to build the manpages.
The config.in patch for sway changes the default terminal to xfce4-terminal, the default launcher to dmenu-wayland, makes firefox launch in wayland mode, adds a message in the window header saying whether it is an xwayland or wayland window, and moves the toolbar to the bottom to make room for the dmenu launcher at the top. You can easily tweak the patch however you want (or start fresh).

I just realized that my original wlroots binary package was built with the unnecessary extra dependency libseat installed, so I have now removed that dependency from my system, rebuilt & uploaded the corrected package.

export GDK_BACKEND="x11"
export QT_QPA_PLATFORM="xcb"

From the plasma thread work with sway too. xwayland 21.1.1 is also a big improvement for sway.
