Improve mouse support
None of the mouse mappings uses a keyboard modifier, making it possible to access the most basic features by only using the mouse. Next/previous image with left button depending on cursor position, middle button for dragging, right button for switching to thumnail mode and wheel for zooming. Users can keep the old behaviour by simply not adapting the changes to the buttons array in config.def.h to their config.h file.
