Set weak mode generally through config object

[AndyOGo]

At the moment each component definition has to be explicitly set to weak mode by /** @define ComponentName; weak */.

It would be a really nice and comfortable feature to change the default mode through config object.

I too would like this option, so I can configure weakness at a higher level via https://github.com/simonsmith/stylelint-selector-bem-pattern
