Fixed callback if DialogFragment called from an other Fragment

[yurezcv]

Good day to you.

I have been trying to use your library in my own project.
And I found out that if I start DialogFragment from an Fragment then I don't receive the interface callback there, but I receive it on Activity which has started this Fragment.
So I decided to add small changes to your library.

Please, check it, if everything is allright I will be very happy to help you :)

Thanks for the patch. I think that's a good idea. Do you think you could also add some tests for around the new behavior?

Since we now have proper checks in place, we no longer need to catch the ClassCastException

@yurezcv Hey, are you still interested in getting this in?

[yurezcv]

@passy Hi, sorry. I have a lot of stuff to do. But I'm interested.
Could you tell me what changes I should apply to get this pull request accepted?
Thank you in advance.

[passy]

@yurezcv No worries, I'm in the same boat. :)

Just the two things mentioned above, ie. the class cast and removing the unnecessary changes to the XML files.

I'm here :)
I didn't get what you mean in "removing unnecessary changes to the XML files.
There are only necessary changes. And I have already removed the class cast, but didn't push it yet.

@yurezcv Cool, the rest is okay the way it is. So it's only left to the class cast. :)

hey,
why got this pull-request never merged???
are you planning to do so?
would urgently need the "DialogFragment called from an other Fragment"-functionality (getTargetFragment())
:)
thanks.

@b3nson I don't have time to pick this up at the moment. Do you want to address the comments? Would be happy to review it.

@passy check pull request here: #72
Only changes to the library-project, removed ClassCastException, no XML-changes.
Is that what you meant?
