[evol] commands management rework #1: moved command parsing into the Mail class, so the CommandParser is now a CommandRunner, and does not have to understand mail parts at all
[evol] added setup.rb installer, with hooks to generate locales and a 'lib/cyborghood/config.rb' file having a new CyborgHood::Config providing with installation paths, and created CyborgHood::Info to contain software general information (rakefile build-depends are then reduced to the minimum)
