Add support for time/Incident Operated Actions

[ChriD]

There should be the Option to start presets or request at a specific time (eg. for Alarm clock) or a specific incident (renderer goes online,...)
For this the c++ backend has to be created

For good control, there should be a web application where we can define a time and a days / activate/deactivate

A major problem will be that the time on the RF Devices may be not correkt. This i have to check

Only some thoughts

  <Trigger type="onZoneAppeareance" zoneId="Wohnzimmer">
    <request>raumserver/controller/loadUri?...</request>
    <request>raumserver/controller/play?...</request>
  </Trigger>
  <Trigger type="onZoneAppeareance" zoneId="Bad">
    <request>raumserver/controller/resumeLastPlayed?...</request>
  </Trigger>
  <Trigger type="onTime" recurence="everyDay" time="0800">
    <request>raumserver/controller/loadPlaylist?...</request>
    <request>raumserver/controller/play?...</request>
  </Trigger>
  <Trigger type="onTime">
    <recurrence day="MO" time="0800/>
    <recurrence day="SA" time="0900/>
    <request>raumserver/controller/loadPlaylist?...</request>
    <request>raumserver/controller/play?...</request>
  </Trigger>
</Triggers>

Of course there will be some problmes with "onZoneAppeareance" how to check this and so on...
