Add automatic driver restarting

Every 15s a background script will check if the viper driver is running and start it again if its not.
This will greatly enhance user experience on devices where Viper is killed sometimes (eg due to OOM).

+  To this day I don't see why one would want to have `Legacy mode` disabled.
   Yes I know it's because a media app should send it's audio session id, but to be honest: Who cares? 
   `Legacy mode` just always works reliably and this is why this installer enables it by default.
   Does anyone remember the time when this option was called "`Process audio session 0`"?
 * **Opt-in instead of Opt-out** \
   `ViPER4Android 2.7` comes with `Crashlytics bug report metrics` enabled by default. Personally I don't like to send bug reports, so I always disable it. I think Opt-in is the way to go here. 
   This is why in this module `Crashlytics` is disabled by default and you may enable if it you wish to.
+* **Keep the vibes alive** \
+  `ViPER4Android` will automatically be restarted if it gets killed. This may be of great convenience on low ram devices, where the OOM-killer is very aggressive, even towards foreground services.
