Add saved lettering presets for our most common setups

Now that each line can have its own lettering style, instead of copying the style from another line every time, I'd love to have saved presets, like preset 1, preset 2, preset 3, for the most common lettering setups we use. Then I could just pick the preset for a line instead of rebuilding or copying it each time. It would speed up entry a lot since we tend to reuse the same few lettering starts over and over.
