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.

26b3b62ed7 DataSource -> DataContainer, so it's more obvious that it isn't the -source- of the data.
the api remains the same however.

a452da7dd2 * removeData method added to DataEngine which allows one to, well, remove data from a source
* passing a null or invalid QVariant to DataSource::setData now results in the removal of the entry if it exists

b86f3f6209 when a data source is requested but does not exist, allow the engine the opportunity to add it by reimplementing dataSourceRequested(const QString&). this makes it trivial to add timezones to the time engine, rss feeds to an rss engine, weather stations to a weather engine or hardware data to solid engines.

2638b6031b * introduce a NullEngine
* return an instance of the NullEngine on engine loading failure; this way applets don't have to test for engine existence and can just assume something gets returned
* DataEngine::isValid() in case someone really cares to know whether they have a non-functional engine (e.g. the NullEngine)

10dd76c794 * when connecting sources, invoke the updated method so they get the current values immediately
* add the ability to limit the number of data sources in an engine; least used items drop off. the algorithm for this is pretty simplistic and not overly scalable, but that's something that can be fixed when we run into problems (e.g. setLimit(1000) or something silly =)

879e215a43 * make DataSource emit the name of the source along with the data; this makes it possible widgets connected to multiple DataSources to have a chance of doing the right thing
* make DataEngine take a QObject in the connect, making DataVisualization somewhere superfluous. unless it ends up doing something useful soon, DataVisualization as a class will be going away.

4c4b013b89 * implement the engine, source and visualization classes
* queue updates so that multiple calls to setData don't result in a storm of updated signals
* some API cleanups, e.g. connect -> connectSource
* provide and install a ServiceType .desktop; this adds the X-EngineName QString symbol. maybe that's too generic.
