Enhance install process by generating config files from templates (#275)

* Add a command to generate configuration examples

Config files are generated from templates (which remplace previous example files).

- solve the issue of hard-to-explain configuration examples
- ease pkg path seeking (avoid it, actually)
- add working defaults for sqlite and unix socket paths (instead of
  /replace/me/path/example)
- move settings comments from default_settings.py to ihatemoney.cfg.j2, as it is
  the one that will be facing user.

* Use generate-config command  in install doc

Also follow the new working defaults of templates for socket and db path.

* Fix doc settings table

On the long term, plaintext tables might destroy humanity.

* Mention templates dir URL in documentation
