Hello world o/

This release is smaller than the last one. I've focused more on tiny
improvements in Sxmo's suspension control, and providing the user with
more internal scripts for control.

For example: here is a single command line to wake the device up every 5
minutes to play a sound, and to keep the device awake while doing so:

$ sxmo_run_periodically.sh -c boottime_alarm 300 sxmo_wakelock.sh run mpv sounds/a_sound.wav

As usual, the community did a lot to detect and to fix bugs, promote
new programs, and to help each-other. Thanks for all!

We also note new initial support for Pine Tab 2, and for Redmi Note 4,
thanks to two new contributors.

As always, remember to run `$ sxmo_migrate.sh` after the reboot to
sync your configs to the latest release. For more info on the
configversion and `$ sxmo_migrate.sh` see the docs:
