Confusing UI option regarding sync in modules

A person was confused by the statement in the 'don't sync' label - they thought clicking it would stop syncing, not realizing the label would self-change. I suppose that is not a clever idea then if people are confused about it.

Changing the label not to change text and using the text "sync?" sounds like an option that is less confusing and the user in question agrees as well.

(23:18:24) AUser: Your Mudlet is annoying me...
(23:19:07) AUser: It doesn't want to save stuff to modules no matter what I do.
(23:21:10) AUser: Oh, nevermind, I see. Apparently the "don't sync' checkbox doesn't actually disable syncing if checked, like common sense would entail. It in fact enables it.

(06:04:40) AUser: It's a checkbox that changes its own label whenever checked/unchecked. A bit confusing.

(06:06:42) AUser: Yeah, but to me it was "obvious" that leaving "don't sync" unchecked would in fact make Mudlet save my stuff.
(06:06:47) AUser: It didn't. Lost a whole hour of code.
