Change format of EventAction properties

Change format of EventAction properties

There were two types of Action= property, one is broadcasting and the
other is changing state. Separate them to have different property name,
Broadcast= and ChangeState=.
 - Action=broadcast -> ActionBroadcast=yes
 - Action=curr,next -> ActionChangeState=curr,next

In addition to this, changed Duration= to clarify its meaning.
 - Duration -> DetectionRangeMsec

This is intermediate patch. Therefore in this version, the property
'ActionBroadcast=yes' won't work properly.
