Leverage .editconfig setup in plugins

[Munter]

http://editorconfig.org is a project that seeks to make different editors reconfigure themselves to follow the conventions of a project by having a plugin read a .editorconfigfile and set its internal configuration to match those setting when editing files in that project.

slint would be a lot more valueable if it could hook directly into these settings to configure the different linting plugins.

This module might be useful: https://github.com/editorconfig/editorconfig-core-js

I like it. Perhaps we should add a special-case for parsing such configurations and give it to specific linting-tools...
