Make Auto-Close Dropdowns optional

[ulilicht]

Hi,

a DropDown always closes when clicked somewhere on the document. It would be great if this would be optional - for example if i put a complex dialog in a dropdown, i want to close it manually. For example: a calendar widget.

Here you can find a Stackoverflow issue which adresses exactly that:
http://stackoverflow.com/questions/23698316/how-to-prevent-an-angular-bootstrap-dropdown-from-closing-unbind-event-which-wa/23723686?noredirect=1#23723686

The corresponding lines in code can be found here:
https://github.com/angular-ui/bootstrap/blob/master/src/dropdown/dropdown.js#L12

It would be great to apply line12 only if the user whished for example by an option.

This sounds like a capability that could easily abused and cause accessibility issues, but if someone submits a PR with tests, I'll gladly review it.
