ImageCacheController class

A controller class to precache a list of provided images on startup.

The images are put onto the image cache to be displayed faster without the need of fetching them on the widget itself which will reduce the loading time of each image. In order to keep the loading time as short as possible and to avoid to much memory alloation on runtime, the precached image should be rather small. Compressing the image or reducing the resolution can help reducing the image size.
