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

The improvements are pretty much the same as between clock and launcher minus the CRC32 check for changes.
Checking for loadWidgets everytime would take between around 200ms and 1000ms, so essentially eating all improvements. Caching the results and just checking the CRC takes 30ms-150ms.
Assuming a 300ms boot there is a 2x to 5x decrease in loading time from launcher. My bloated bangle install takes a lot longer than 300ms to boot ;)

I would not install this by default or integrate in firmware at this point in time either. Since it has no dependencies and "only" applies what is already done in .bootcde to other loads it should not have that many side effects (there are probably some with other apps redefining load). After leaving an app there is still a full reload every time as long as apps do not widely implement remove.
