StringTree.__getitem__() returned the node, now return its value
child instead. That's nicer and closer to the expected behaviour, as
it supports StringTree usage as a key-value store for configuration
or so. It breaks the existing API, but I think I have fixed the only
pace where it was used: jw-grammar/grammar.py.

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.

Add support for adding children of type StringTree. If a StringTree
argument is passed to .add(), this should do the right thing. It
makes use of the newly added .__add_children() method and involves
quite a bit of hairy case distinctions.

parse() and read() up to present automatically set the root content
of a StringTree object to "root". This can now be optionally defined
by the "root_content" keyword argument.

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.

Add leading underscore to variables that should not be visible
outside of log.py. Also do some indentation beautification.

object_builtin_name() is meant to derive an object name from its
class name. Doesn't work well, but adding the code nonetheless for
improving it later.

PROJECTS_DIR is a final version of where the projects to be compiled against
are. DEV_PROJECTS_DIR is merely a candidate, used in proj.mk, currently only
there.

- Change "=" assignment to "?="
- Prepend $(BUILD_TOOLS_PREFIX) to /opt/jw-build
