Bug#499930: [Patch] make offlineimap tollerant of man's capitalization

[Jason Woofenden <jason@jasonwoof.com>]

I too fell into the trap of copying the man-page's headline. This
is especially confusing, since the setting I was using (TTY.TTYUI)
is-all caps (so I figured they all were supposed to be all-caps).

Since it is not possible/reasonable to fix the man page, please
make offlineimap accept all-caps arguments for the ui setting.

Attached is a patch to do just that.

I hope you will include it in future releases.

Thank you,     - Jason
