This file looks ignored by mistake

We need to include this file but in a way that Typescript is happy with if the values are commented out.

Thanks for your work on this.

We already support loading settings from a bslint.json file, so I don't think we should be adding another type of config (config.local). You should be able to define this new structure within existing bslint.json design. So I think the files in src/config/ should all be removed.

Here's how the config file is loaded via the CLI:

bslint/src/cli.ts

Line 32 in a650d6f

const config = normalizeConfig(options);

And here's how the config is loaded via the brighterscript plugins (and language server):

bslint/src/util.ts

Line 114 in a650d6f

const { rules, fix, checkUsage, globals, ignores } = normalizeConfig(program.options);

I'd envision this being added as some subtype of the rules, maybe like this (with defaults set if the user didn't provide these). I'm open to suggestions on the exact structure. @elsassph any thoughts?

{
    "color-cert": {
        "severity": "error",
         "colors": {
             "broadcastSafe": {
                "black": "#161616",
                "white": "#EBEBEB"
            }
        }
    }
 }

Will take a look when I get some time. :)
