Basic UI just got noisier

[John Wiegley]

I use the Basic UI, and until now it only ever printed relevant information.
As of 6.5.x it now displays this:

--8<---------------cut here---------------start------------->8---
Next refresh in 15.0 minutes
Next refresh in 14.0 minutes
Next refresh in 13.0 minutes
Next refresh in 12.0 minutes
Next refresh in 11.0 minutes
Next refresh in 10.0 minutes
Next refresh in 9.0 minutes
Next refresh in 8.0 minutes
Next refresh in 7.0 minutes
Next refresh in 6.0 minutes
Next refresh in 5.0 minutes
Next refresh in 4.0 minutes
Next refresh in 3.0 minutes
--8<---------------cut here---------------end--------------->8---

Given the manner in which I run Offlineimap, this is pure distraction and has
no value.  Can we add a config option to disable this kind of output?

Thanks,
  John
