Updated README; added cropping information to the text output (outfile);
camera movement is now controlled via mouse buttons (forgot to mention
this in the last commit).
Simplified implementation of cropping between ahsoka and her frame
server by storing all information related to crop dimensions in the
global STATE fields "crop_preview" and "crop_applied", which are also
named much more self-explanatory. As a result the correct cropping
information is now printed to outfile even after more than one cropping
operation.
Unified the status log output descriptors to 3 char prefixes (IDX for
index, CRP for crop, PRE for prefix etc) and added a function for prefix
modifications that automatically reports changes to the log.
