Enhancement: Embed default config file into the binary

[al3xandros]

I would like to suggest a feature enhancement that embeds the default configuration files
(default.yaml and traditional.yaml) into the binary.

Rational:

• A valid configuration file suitable for the version of the binary would be always available if needed.
• The default config files can act as a quick reference for creating custom configs.

Hmm, embed in what sense? Like as a string that could be output by ergo genconfig or similar?

Oh, I see your commit now, that's nice. I'll make my own PR
