Translate GDK_KEY_KP_Decimal according to locale

It makes sense that you should be able to type numbers that are
correctly formatted and parsable according to the current locale,
using just the keypad. This patch makes it so by translating
GDK_KEY_KP_Decimal to the decimal separator for the current locale,
instead of hardcoding a '.'.
