changes to support amcrest AD110 and other small bugfixes

[blademckain]

to resolve the requests made here
and to fix other small bugfixes

the main change is in the function

def event_actions(self, eventcodes, retries=None, timeout_cmd=None):

now the tuple never returns
(event name, Start)
but return
(event name, payload)

where payload contains all event information
