* Make toggling Gyro events more robust
Actually ask to turn it on/off depending on the setting, instead of a
blind toggle
A quick succession of suspend/resume events could otherwise leave it
in an unexpected state (i.e., off when it should have been on).
* Fix the Touch input probe on Trilogy devices that depend on the touch_probe_ev_epoch_time quirk (fix#630)
* Expose a "Pageturn button inversion" feature in the Navigation menu (for all devices with keys) (fix#4446)
* Allow ignoring the accelerometer on the Forma (Screen > Ignore accelerometer rotation events; also available from the Gesture Manager) (fix#4451)
* Fix SleepCover handling on the Forma (fix#4457)
* Make isWifiOn a tiny bit more accurate (check the actual WiFi module instead of sdio_wifi_pwr)
* Move all flash related Screen options to the eInk submenu
