add fade-in and fade-out support for modal

[andyczerwonka]

With raw bootstrap, you can control how the modal dialog appears, For example:

class="modal hide fade"

gives a pleasant fade-in/out to the dialog. Is there a plan to support that kind of behaviour?

@andyczerwonka Yep, we would like to support all the options of the bootstrap's modal. Having said this there is a very, very cool PR waiting to be merged: #36 which will add a much better way of controlling dialogs. So, I want to merge this PR first, push the release and then work on the remaining stuff.

But yeh, keeping it open, we want to support all the options of the modal.

@andyczerwonka so, the mentioned dialog service landed in the repo and is available on the demo page:
http://angular-ui.github.com/bootstrap

I would encourage you to give it a try and see how it works for you. In the longer run we should probably decommission the modal directive and redirect people to the $dialog service.

Going to close this one, feel free to open a separate bug for the $dialog service if things don't work for you as expected.

There's also a way to add a fade out effect (or are you planning to add fade out effect)?
Because fade effect is applied only during the opening of the modal, and not also when closing...
