akuma06 5376b9e271 New config files (#854)
* New config files

As decided, config files are parsed at runtime.
I decided to go for YAML config files because there can be comments in
it.
There are 2 files:
* config/default_config.yml <= which shouldn't be edited unless we add a
config parameter
* config/config.yml <= which is the user-defined config. This file
shouldn't be commited

Changed every call to config.XXX to config.Conf.XXX (look to the new
stucture of config in config/types.go)

Of course, putting config parameters in config.yml overrides config in
config_default.yml. You don't have to put everything in it, just add
what you want to override.

* Fixing test

Replacing conf.New by config.Conf

* Fixing call to config.Conf to config.Config{} in test files

* Might have fixed testing with this

Printf instead of Fatalf

* Renaming config.yml in example file

* Forbid commiting config.yml

* Should be now fixed

* Do not need this file anymore
