jw.build.cmds: Move build.cmds -> cmds.projects

Reorganize the Python module structure. Placing the command classes
under jw.cmds.projects instead of jw.build.cmds will allow to add a
nested command structure, with the current commands, being mostly
related to building software, found below a "projects" toplevel
command.

Other conceivable commands could be "package" for packaging, or
"distro" for commands wrapping the distribution's package manager.
