[cleanup] moved base require files in 'lib/cyborghood/base'
[cleanup] split 'lib/cyborghood/base.rb' and reorganized requires a bit
[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)
