Title: use configurable font sizes for default button and ToggleButton

Currently the default button and the ToggleButton have fixed font sizes. I introduced a new resource so you can change it (in my app I use larger fonts).

There are some more fixed font sizes, but since I don't use them, I didn't touched them.
