Fix for longer font names that do not fit in the font-selector

[nickvankollenburg-hue]

I became a bit annoyed with longer fontnames not being properly visible, as a result of the font-selector having a fixed-width.

As I do appreciate the fixed width - since it avoids having a jumpy toolbar - I've added some CSS to create an ellipsis.
This makes the Quill visuals a lot more professional.

The CSS works for both Bubble and Snow.
(It doesn't change the selector color, I just happend to hover it when making the second printscreen)

/* Font picker label fix for Quill 2.0.3: Snow and Bubble.
   Load after the relevant Quill theme stylesheet. */

.ql-snow .ql-picker.ql-font .ql-picker-label,
.ql-bubble .ql-picker.ql-font .ql-picker-label {
    padding-right: 24px;
}

.ql-snow .ql-picker.ql-font .ql-picker-label::before,
.ql-bubble .ql-picker.ql-font .ql-picker-label::before {
    display: block;
    width: 100%;
    overflow: hidden;
    white-space: nowrap;
    text-overflow: ellipsis;
}
