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

Actually I got the widgets to render and behave mostly as expected. There is still something strange going on. Imageclock always loads the widgets and then replaces the draw functions with functions doing nothing and restores them as needed (showing the widgets/switching to launcher). Essentially that hinges on a showWidgets variable, which should be false on every initialization, but the widgets visibility survives the switch between clock and launcher. Widgets shown on clock are still shown after switching to launcher and back.
I would expect the showWidgets variable to be removed and reinitialized to false, since it lives in the block scope. The memory after GC is always the same for launcher and clock, so probably no major leaks. Launcher uses less memory than clock, as expected.
The behaviour is actually quite nice, but I don't understand why it works that way. Printing the showWidgets variable at the top of the block does not work, as it is not yet defined.
