some cleanup in the web interface and inet server
added some images/screenshot
big change on how settings are loaded

settings are now more dynamic, no overhead information. online data
removed and integrated in normal sensors. updated readme. webinterface
is broken at the moment
another overhaul
minor timing tests
move the sensor interval function to the scheduler

this prevents misbehaving sensors to crash the main thread since all
jobs in apscheduler are threaded (at least, that is the idea :) test
over 1 night looks ok for now.
bug fixes
recover
