[Feature] Global defaults

[jadell]

We have multiple templates using vuebar, and repeated config in each, even within the same template.

It would be useful to set up global default config when including the mixin in Vue. Of course, options included with the directive in the template should override global defaults.

Something like:

import Vuebar from 'vuebar';
Vue.use(Vuebar, {
  defaults: {
    el1Class: 'foo',
    useScrollbarPseudo: true,
    unselectableBody: false
    // etc...
  }
});

Don't have time to try my hand at this and make a PR right now, but just leaving a note that this would be a useful addition.

Hi @jadell, this looks interesting, thanks! I'll look into incorporating it into upcoming Vuebar 2.0.

@DominikSerafin I'm trying to change the default class name, but it looks like it ain't working?

Vue.use(Vuebar, { defaults: { el1Class: 'foo' } });
