Import resolution about boussole HOT 2 OPEN

For sanity, i checked compilation with Foundation, Bootstrap and Bulma from their node modules and everything is fine for compile and watch mode.

But as stated from issue detail, an exception is raised for conflicts, if the Sass project import Foundation and also contains a components/_badge.scss file, it make a conflict with the one from Foundation.

Plan:

• Error for conflict should stay as a feature which can be disabled from a setting, it seems safe to turn it off on the next version;
• Resolution for the same pattern should have order base on proximity (a source from project win again a source from imported module) and then format extension (scss > sass > css);
• Libraries priority comes from order in library paths setting, so user can force a library to win, no matter alphabetical order or anything else;
• There is no need of a new engine, since conflict resolution error will just be disabled. We will have to add some new code for resolution discovering in inntrospection when error is disabled;
• "~" feature will be added from a new settings like base_modules for a path to search from import pattern, not sure for final implementation with the introspection. If need it will be move to a distinct issue to avoid blocking this one;
