Let the user choose which reveal animation to run #100
Description
As of version 1.2.2, if we choose to animate the search view when we're opening it, the animation type is decided based on the API level. If the device is running a pre-lollipop android, it'll use fade-in and fade-out, for api 21+ it'll use circular reveal.
It might be interesting to let the user choose what kind of animation should be used, if any.
Possible problems:
- CircularReveal won't work on pre-lollipop. Unless we get the animation from a third party lib, but it'll just make MSV bigger.
- Should we add custom animations? If so, we should also consider a "custom" animation type.
