QGalleroob allows to search galleries and images and browse collections
of those.

rationale: proper build needs to go through setup.py anyhow
by renaming Makefile to a less common name, we avoid people building by mistakes
only the makefile-driven part.

This also helps distribution heuristics when guessing how to auto-build
packages (e.g. Debian dh_auto_build)

This allows running "make clean", or "make all" without using the
setup.py.
