Select menus don't work on custom toolbars without theme

[saw]

Quill adds preventDefault() on mousedown to the toolbar container, which prevents select menus from opening on mousedown. With a theme this doesn't matter because you have the picker. I understand this is done to keep the editor from blurring, but it would be nice to be able to use quill without a theme at all without having to re-implement the toolbar completely.

2. Try and pick a size.

Yes this has been fixed and should be in the next release #997
