espalarm Code

Try to get a grip on reconnects

Alarm : call screen refresh / button activation in the right order.
OledButton : add a (#ifdeffed out) method to debug drawString() in the superclass.
All : rename Active() method to setActive()

remove dead code

Fix calculation of average loop time

Hush up about duplicate seqno. Add more info in network query.

Small bugfix

Small updates

Clear screen before button redraw. This is required for the button reshuffling that we do.

Move a function from components/espmqtt to here to prevent gettimeofday() calls.

Platform_esp_idf.c : #if away a function, move it to main/StableTime.cpp in which we implement
this without the infamous gettimeofday() call. Remember that we have plenty of evidence
that this call blocks/freezes the app periodically. No recovery known from this situation.
transport_ssl.c : avoid duplicate name conflict.
