Restart xochitl using remux and oxide API instead of restarting everything.

Instead of restarting all of the currently running applications, even if xochitl isn't running, this code should be a little smarter and instead use the remux or oxide APIs to restart the xochitl application if it's running.

Remux launch API: https://github.com/rmkit-dev/rmkit/tree/master/src/remux#launch-api-020 Example:

if killall -q -0 xochitl; then
  killall -SIGCONT xochitl
  killall xochitl
  i=0
  while killall -q -0 xochitl; do
    sleep 1;
    i=$((i+1))
    if [[ "$i" -gt 5 ]]; then
      killall -9 xochitl
    fi
  done
fi
echo 'launch xochitl' > /run/remux.api

Oxide Apps API: https://oxide.eeems.codes/documentation/api/02_apps.html Oxide CLI tool for interacting with the API: https://oxide.eeems.codes/documentation/01_usage.html#examples-of-usage Example:

app=$(rot apps get runningApplications | jq -r '.xochitl' | sed 's|/codes/eeems/oxide1/||')
if [[ "${app}" != "null" ]]; then
  rot -o Application:$app apps call stop
  rot -o Application:$app apps call launch
fi
