Allow initialization of configuration file with current default values

[AdmiringWorm]

Detailed Description

Currently the init verb only allows creating a new configuration file with commented out example values.
This may cause some confusion when the default values do not match the example values, so I suggest adding an argument to allow generating a full configuration file that will be filled with the current values already used by GRM (ie the default values).

Context

This change can be important to reduce the confusion of the generated configuration file, and the actual values that are used by GRM, as well as preventing allowing users to have a fully generated configuration file without the need to type everything out themself.

Possible Implementation

Your Environment

• Version Used: 0.11.0
• Edition Used (.NET Core, .NET Framework): Any
• Operating System and version (Windows 10, Ubuntu 18.04): Any

@AdmiringWorm this seems like it would be a good addition to me.
