settings: font size

[mickroll]

This app is really useful, not only for shopping lists, but for all kind of TODO lists. My entries have a bit more text than a typical "milk, eggs, beer" - shopping list, so it would be great to be able to change the size of the font that is used to render the lists. One setting for all lists would fit most usecases. I see no need for a per-list setting.

Also, this way all types of devices would be better supported, as the wall-mounted tablet in the kitchen and a small sized smartphone have quite different requirements on displayed font size, even if they have the same screen-resolution.
