Add option to ignore file or project

[brandonkal]

I have a jinja template file, specifically wp-config.j2 that is highlighted as PHP, as it is mostly PHP with some jinja inserted like so:

define('DB_NAME', '{{ DB_NAME }}');

/* Authentication Unique Keys and Salts. */
{{ salts }}

I would like to ignore this file from linting, but that does not seem to be an option with linter-php.

Setting "Ignore files matching this Glob" for linter works but it would be nice to set this in the linter-php package.

**/*.{j2,min.{js,css}}
