add template for a settings file inside a pbo

[commy2]

When merged this pull request will:

• Adds a template that can be binarized to have a signed settings file inside a PBO
• Can be used to enforce settings for a whole repository

@PabstMirror Would that work for you?

That looks handy!

...enforce settings for a whole repository

The term "repository" is confusing. (It is not a term usually associated with playing the game. A user of CBA may wonder "what/where is a/the 'repository'?)

[commy2]

Other suggestion? "modpack" sounds weird.

[Killswitch00]

How about "static settings addon" instead of "repository settings file".

The template shows an example of an addon that can be used to enforce settings for a mod/addon collection or a mission/mission type.

Looks good. Needs documentation that users can read (what it is, what it can be used for and so on). This could be in the form of a separate text file in the templates folder or placed in a comment header in the config.cpp

Ok, so no docs then.
