When your token expires, Tako doesn't accept the new one

[grrowl]

Regenerating a token at the provided link, pasting it into the box, then when you click "Save" nothing happens. It seems to save the token, because refreshing the page then works.

Github is now strongly encouraging users to set expiration dates for the tokens (it's 30 days by default) so this is going to hit and confuse a lot of people. You could probably just do a full page refresh once the token is persisted without too much impact
