Don't let all <thead> checkboxes to function as selector
|Reported by:||Cimmo||Owned by:|
In my plugin: Cimy User Extra Fields I use checkboxes on <thead> but unclukily one function in common.js is picking up any click coming from any checkbox from <thead> and <tfoot>
Since I think this is too much, we can maybe take only the one from '.check-column' if this doesn't break anything else.
Here is my patch, please review it and let me know.
