Large refactoring of the Java code in bootstrap.

Broke off each of the action commands into there own handlers.
AndroidCommandSelector has been rewritten and integrated into Find, and
other places.

Added java doc to all classes, and formatting changes based on
bootstraponline's settings.

Conflicts:
