I've just upgraded to Vuetify 2.0 and my fonts are totally broken.
I've managed to change the font on the project by:

```css
.v-application {
    font-family: 'Montserrat', sans-serif!important;
}

```

But the headings that have applied classes like .display-1, .display-2 are still taking the Vuetify default (Roboto) because it has an !important in the Vuetify default styles.

How could I change the font for the entire project, overriding Vuetify's default?
