Oct. 27

A collection of small updates.

printoxx 2.1: drag and drop files from the file chooser dialog (old click method was also retained).

zfuncs 2.27: drag_drop_connect() function was upgraded to support the above printoxx change.

picpuz 2.1: the image thumbnail gallery is no longer opened at startup (was unconventional and confusing).

Makefile for all applications was tuned to better manage desktop menus.
