Global config

[Szymon-dziewonski]

I think that would be nice to have global configuration with for example classes like here https://github.com/Akryum/v-tooltip
In our project we have css-modules with generating class so I would prefer to have my own generated classes on your component. I see its possible to add classes on component but when I would have global config then I would not need to create wrapper on your component.

Also why there are some fonts added to styles? I think any theme styles like icons should be options, with it bundle grow up.

Overall component looks nice
Thanks
