Support regex content in blueprints

[netomi]

From OP:

I would like to use a regex in the content. This way i could restrict general parts of a file but open it for project specific parts using the regex pattern

Regex pattern:

Expecting you have a . editorconfig file in each repo.
That describes the general formatting and should be same over all repos.
But some repos need additional settings that are spectial to this repo and are not relevant to other repos.
You will need a Blueprint that defines the first lines and then allowes optional things using regex.
