Add font/text-change ability to WYSIWYG/markdown with buttons

I'd love to have more choices to color text. Only highlight is rather limited choice.

I want to use Joplin to create my own English grammar notebook and more options to distinguish text is essential for me.

Please, Joplin developers, bear in mind that there are different use-cases how users use your app.

Actually, it would be nice to have such icons to color font as they are in for example LibreOffice Writer and with the same functionality. I believe it is a standard way of handling coloring text in many applications.
