Subject: Add support for squared thumbnails

Disabled by default, only very simple center crop implemented.
The SQUARED_SIMPLE_SHAVE_AMOUNT constant may be slightly adjusted
according to future experience. It's a really dumb algorithm which
may not be suitable for every picture.

Looking for a fast and smart algorithm to determine image weight center
and radius, i.e. focus on object of interest. The OpenCV's face recognition
features are worth to test and consider, though I fear the speed issues.
