Code is added to switch between Kobo Aura (Phoenix) and others.
`ReaderFrontLight`, `self.ges_events` and the `function ReaderFrontLight:onAdjust` are now different for Kobo Aura. This enables me to do a two-fingered-pan over approx 1/4 Screenheight to change from full on to full off.
The difference to the default implementation is that both the `rate` and the `msg` are omitted and the `steps` are different.
FURTHER ROOM FOR IMPROVEMENT: It would be an improvement to get a final message after the two-fingered-pan is done stating the achieved setting.

This should finish the work to make all globals to local variables.
That allows LuaJIT to properly compile things by interning the
references to the relevant parts (rather than looking up globals
all the time which stops a trace).
