Unify configuration into private/BocaConfig.class.php
Remove inclusion of 'version.php', 'version', and 'versionnum.php'.
Remove bogus files 'php.php' and 'test.php'.
Remove tools. We won't rely anymore on machines specially configured to use BOCA (at least not regarding networking).
Remove required to run 'createdb.php' as 'root'.
Merge branch 'master' of github.com:magsilva/boca
