* Removed scripts/run-from-source.sh as it's now redundant.
* Added `--background` optional argument, only for when using
`--from-source` to start-eddn-service. The script will leave the
service in the foreground, no output redirection, without it.
It tells you the PID of the process when it's backgrounded, as well as
placing it in the appropriate .pid file.
* Also now stores PID in per-service file in configured logs directory.
* Swapped the environment arg and service so it's, e.g. "live gateway"
now.
* New optional third arg `--from-source` to... run from source, not
installed files. The script *will* exit and redirect output, but
record the PID and tell you it.
New SRC_DIR in the config files to know where to run from.
* <hr> between sections
* Document the ports that *must* be open to the internet.
* Apache will require the proxy_http module.
* Move the github clone earlier in instructions, as part of ensuring
paths exist when they should.
* Note about needing to do hostname and port substitutions in monitor
files if not using the standard values.
* Link to other sections where appropriate.
* Use the "make an explicit Bottle() and use it" change.
* Use app.route with OPTIONS in method= list.
* Remove extraneous setting of Access-Control-Allow-Origin header.
The hope is this can be used to easily switch between live, beta and dev
for setup.py without worrying that a git merge will suddenly turn beta
into dev, or live into beta or dev.
* Have 'dev' and 'live' components to many paths and file names.
* Have separate dev/live systemd start script configs.
* Have the systemd start script take a dev/live second argument.
* Try to ensure permissions on 'web' files by explicitly setting umask.
* Let's stick with Bourne Shell, not BASH-isms.
* If we make everything use ~/eddn/python-venv symbolic link then
there's less to update in the future.
* 'monitor' files are for the web page showing status/stats.
* 'schema' files are a publically available copy of the schemas in-use.
* 'systemd' files are the start-<service> script and its config file.
