[WIP] Allow building with GTK+ 3.16+.
Set CMake option `ENABLE_GTK3` to `ON` to build with GTK+ 3.0. In GTK3 mode: - Use `GtkGrid` instead of `GtkTable` - Don't use `GtkMisc` to set `GtkLabel`'s alignments - `PianoKeyboard`'s draw() code still needs to be refactored (doesn't show key presses). - Grab keyboard functionality still needs to be ported (doesn't work yet).
