Unification of time and duration units in entity configuration and states

[tuxpoldo]

All times and durations in entity states and entity configurations should be expressed in milliseconds in order to maintain a standard.

This does not affect internal measurements like:

• Scheduler registrations (expressed in microseconds)
• Performance measurements
• Other internal stuff

@domschl : Consider changing this in ms:
sensorprocessor( int smoothIntervall = 5, int pollTimeSec = 60, float eps = 0.1 )
