jwutils.Cmd.add_subcommands() had two issues. First, it failed for
more than one command, and with that fixed, it only added the first
command of a list of commands passed as an argument. This commit
fixes both issues and leaves some logging and cleanup in place, which
was used during debugging.

Cmds.cmds was sometimes empty, so fix that and make sure it points to
the Cmds instance it was crated by. Actually the name of the Cmds
class is a bad pick, should have been App or something, so to add
.app, too, as a path for future compatibility.

Add method jwutils.Cmd.add_subcommands(). cmd.add_subcommands(C) will
parse and invoke C as a subcommand of cmd, if C is of type jwutils.cmd.

jwutils.log.set_flags() and .set_level() is not set until after all
commands are loaded. This can make debugging complicated. OTOH,
command-line parsing is also not done until all commands are loaded,
because they define the command line options. This commit adds some
poor man's command line parsing for fetching --log-level and
--log-flags only, and applying them before the commands are all
loaded.

This commit makee Cmds run all sub-commands in an asyncio event loop.
The event loop is currently passed to the commands, which seems
unnecessary and looks like it's using a feature which is bound to be
deprecated in the future.

Changes in Python 3 that made the code choke:
o basestring is merged into str
o print() needs parentesis
o Class inheritance syntax changed
o Abstract baseclass (ABCMeta) syntax changed
o map.iteritems() is replaced by map.items()
o Inconsistent use of tabs and spaces are no longer tolerated

run_sub_commands() was the only way to access subcommands up to now,
Cmds.run() adds another interface, an object as a place to add
customizations affecting all commands, e.g. global command line
options.
