Jan Lindemann ac583f76e1 build.cmds: Move build.App.cmd_xxx() here
For every cmd_xxx() method in build.App, create a class that's
instatiated for running the respective command. This has the
advantage of making App.py smaller (and faster), and having smaller,
more maintainable command modules adhering to a common interface.
