Add support for aliased owfs sensors (#6043) 

* Support aliased owfs sensors

Current implementation does not support OneWire OWFS sensors that are aliased by OWFS alias.txt file:
http://owfs.org/index.php?page=aliases
Assumption is that folder name == sensor address

This change reads the supported families from owfs "family" file and adds both aliased and unaliased sensors.
(this approach also skips the "management" folders.. eg simultaenous, bus, alarm, statistics etc. For example when adding "simultaneous" as sensor (it also has "temperature" file) then owfs crashes)

* Update onewire.py
