* Fix command hint to generate a config file

When trying to start Synapse without a config file, it will complain
and give a hint towards what command to run. This hinted command
is missing the "report_stats" parameter, which is required with either
yes or no value. Add this to the command.

Not an ideal situation but makes the given command work without the
user getting another error, even though it might be unclear what
"report_stats" represents.

We should use the same python to start the workers as we do for the main
synapse (ie, the same one used to run synctl.)

Assume isatty is always defined, and catch AttributeError. Also don't bother checking colour==Normal

symlinks apparently break setuptools on python3 and alpine
(https://bugs.python.org/issue31940), so let's stop using a symlink and just
use the file directly.

Fix ncorrect ports in documentation and add notes on how generate-config also generates certs bound to whatever hostname you give with --generate-config.

SYN-87 #resolved

Make instructions synctl gives for generateing a config file actuall generate a config file. Also, make synctil run synapse correctly by invoking a module such that the path is correct to pull in other bits from the working directory rather than requiring them to be on the PYTHONPATH (which would lead to people being very confused when they edit source in the working directory and their changes do not take effect).

Don't autogen config in synctl for the same reasons we don't turn of --generate-config by default on the homeserver - it is liable to confuse people who have moved the config file or have chosen a non standard location.

Also, don't override log file location.
