kcms/keyboard: Increase maximum repeat rate

The current maximum configurable keyboard auto-repeat rate of 100 is
too conservative; change it to 200.

For me personally, repeat of about 130/s is ideal. Increasing much
beyond 130 is too fast for me (too hard to move cursor short distances).
I set the maximum to 200 on the assumption that there are people with
much faster reflexes than me, but 200 "ought to be enough for anybody".
