Removes the Level textbox behavior that resets the text to "1" when the textbox is empty. Can be left empty, and will be treated as 1 when values are stored.
Adds an accessibility label for the "Make Shiny" button
Adds an accessibility description and enter/space keypress to toggle similar to the click event.
For determining if something is shiny, if the Shiny button is not tab-able, it is shiny. I wasn't able to get the Shiny star/square indicator to be able to be tabbed to for some reason.
