ProvinceMapper-1.0.4

This release adds menu items that replicate all existing functions (except changing zoom levels). This should help make the existing options more discoverable.

It also makes the + and - buttons move mappings up and down. However, because entering any character zooms to the first mapping starting with that character, - also inadvertently adds a mapping and moves your selection.

There's also been some light code cleanup, but nothing exciting.
