default to patch releases for messages which do not contain a specific emoji, or any unlisted emoji

[ThommyH]

We want to rollout gitmojis for the dev teams but we have the requirement to always create a patch version no matter what. The reason for that is, that server-side pre commit hooks are cumbersome to setup for >100 projects and relying on pre commit hooks on the client side is not reliable.

Therefore, to not bother with it too much, we would like to setup a default patch version for every commit. Similar discussions happened in the commit analyzer project .
