Implemented time spin control which is like spin control, but shows and allows to edit time string in "hh:mm PM/AM" format.
Implemented according to the WLRS spec.
Simple perpetual loading indicator a la MacOS X or YouTube.
Implements spinning by changing pre-defined images.
The images are hardcoded, shared by all instances of the widget.
Number of rotations per second can be changed via params.
