Django-supervisor

* Fix handling of "--" in options list.
* Explicitly use {{ PYTHON }} {{ PROJECT_DIR }}/manage.py in all default
recipes. Using just {{ PROJECT_DIR }}/manage.py can be troublesome if
the ! line in manage.py doesn't match the version of python you're
using on the command-line.

* Stop manage.py trying to parse options intended for supervisorctl.
* Ensure the auto-generated username is less than 8 characters. (This
works around an authentication bug in some versions of supervisord).
* Many tweaks to the default configuration based on early user feedback.

* More flexibility in selecting programs via command-line options. You
can now override both the "autostart" and "exclude" options:
-l/--launch => launch program automatically on startup
-n/--nolaunch => don't launch automatically, but keep in config
-x/--exclude => entirely remove program from the config
-i/--include => keep program from the config
* Rename "autorestart" to "autoreload" since the former is an existing
supervisord option that means something very different. Also:
* Allow selecting a subset of processes to auto-relod, via config file
or command-line switch.
* Add --noreload command-line switch to disable the autoreloader
* Add a contrib supervisord.conf for django-ztask.
* Add "getconfig" command, to print the final merged config to stdout.

* In debug mode, provide an "autorestart" process that watches your code
and restarts all processes when something changes.
* project-specific config: allow pre-specified [program] sections to be
completely removed from the config, by specifying exclude=true.
* project-specific config: allow a [program:__overrides__] section to
override options in all program sections at once. Useful for things
like globally switching autostart on/off or redirecting stderr.
* app-specific config files: use only one of management/supervisord.conf
or contrib/<appname>/supervisord.conf, never both. This prevent us
from accidentally conflicting with settings specified by app authors.

* Initial release; you might say *everything* has changed.
