Default [Library] FloatingActionButton 2.1+ (FaizMalkani + Quinny898)

I merged these two project into one and fixed some bugs:
1. - only 4.3+
2. - I think is not completed or it need special instructions to use doesn't matter, it provides functions to work on 2.1+

Now in one, you have all goodies in one project. I fixed problem with preview so you can now see how it will look after build.
More info and instrucions:

I want make it only jar file but dont have time now, probably I'll do it in coming week.
