Mustafa Quraish d28fb8926f PixelPaint: Add mechanism for tools to use keyboard shortcuts ...

There are quite a few tools that might want to change certain values
based on consistent keyboard shortcuts. This commit allows tools to
hook up a "primary" and "secondary" slider with the base `Tool`
class, which can then handle updating those sliders with the common
shortcuts.

Note that any derived classes that want to override the `on_keydown`
function will manually need to call `Tool::on_keydown()`.
