App.is_installed(): Add method

Browse source 
The installed state of a project is judged by the proofs of installation,
which differ per subpackage: make/project.conf in the dev tree or /opt
proves the -devel package or a buildable checkout, a VERSION file in the
project directory or /usr/share/doc/packages the -run package.

Add is_installed(), which answers the proof question for a given subpackage
by searching the per-subpackage locations.
