6ffbc459ad - when an intervalled visualization triggers an update, but the update is async, we queue up to trigger updated when the data _actually_ arrives. 
- timestamp sources on update so we don't over update them due to multiple visualizations hammering on it. improves our tick situation even more.

e15c950bc3 introduce interval alignment, so it is possible to align a time interval to the minute or hour (we can add arbitrary ones to the mix should we choose; e.g. "every 10 mins" or whatever..but there needs to be good use cases =) 
this is needed by clocks, as the obvious example, since "once a minute" isn't enough: it needs to be once a minute *on* the minute

fc89eff135 first run at per-visualization timeouts, as per the design worked out on panel-devel. 
i'm sure there are several bugs at this point (so don't try and use it quite yet ;) but most importantly:

- all methods are implemented
- it compiles ;)
- it does not have any negative impact on existing engines and applets as they currently are written

next will be to put it all through its paces, starting with the time engine and analog clock applet. i may not get to that until tomorrow, hoever.

this commit also fixed a number of buglettes along the way that had creeped in, e.g. not properly connecting all signals in connectAllSources (moved that ccode to the Private class to avoid code dupe and similar bugs in the future)

8ccfa4e4dd QMetaObject::invokeMethod is called incorrectly in 
DataEngine::connectSource / DataEngine::connectAllSources

also: If a DataEngine fails to create the source in
sourceRequested(source), an empty source is created in d->source(source)
and then used during QMetaObject::invokeMethod, which calls updated for
the applet.
Better: don't create the source. This forces DataEngines to create the
source.
