POC - Combining BW Clock and Desktop Launcher to spend less time "Loading..."

Perhaps we should consider making drawWidgets actually only queue up a redraw, so if it gets called >1 time before we next idle there is only ever one full redraw?

One call will not be enough when at least one widget changes it's width during draw. But we can do with one or two draws, first draw executed instantly and then capture all other drawWidgets and queue one for next idle. I have tried it and it works fine.

The changes to the 4 widgets are working well, I could remove about half of the code of widgetupdate while keeping it working the same way. It now essentially only handles automatically hiding of the widgets and the queuing of drawWidgets
