Autofocus on Modal opened

[algorithme]

Hi,

When a modal opens, we would like to be able to set the focus to the first input. But your implementation of the directive hijack this behaviour.

ui-bootsrap-tpls-0.10.0.js line 1459
// focus a freshly-opened modal
element[0].focus();

This automatically set the focus to the opening window and the only solution we've found to set it to the first input was to delay the action using a $timeout call.

Is there any other solution? (registering a callback or listening to events?)

Would it be possible that we provide you with an improved version with a default value using the current behaviour and the availability to disable it?
