Change API design to support Drawables/Colors/... instead of just resource IDs

[MFlisar]

Currently you use a builder to setup the simple slide. As they are used for creating a fragment, you're limited in what you can define (like you can only define image resources, but can't define a drawable instead).

For surpassing this limitation, it would be nice to add an interface that the parent activity can implement and that can provide additional data (like for example a Drawable for the icon) and much more of course.

What do you think about that?

This means, we can use the SimpeSlide for many more usecases and make it much more flexible, drawback is, me must add an id for each SimpleSlide to identify the slide in the interfaces functions...

PS: check out my repo clone, I have uploaded a very basic change already just to DEMONSTRATE what I mean. Changes are minimal currently...

This may be a thing to have in a major release as I would have to change the API to make the interaction as intuitive as possible.

My clone currently does fully support this (inclusive fast and easy extension of views, for example adding a progress bar or a checkbox to the inner LinearLayout container). I can make a pull request and you just comment on it, if you want some changes...

It's fine if you do it yourself as well when you have time, my clone is working perfectly fine for me now as well...

Yeah, a PR would be great!

@MFlisar If you’re able to submit a PR, we’d love that!

Here's the according PR - #195 - it's already merged... And here's the renamed interface for the simple slide of the current master: https://github.com/heinrichreimer/material-intro/blob/master/library/src/main/java/com/heinrichreimersoftware/materialintro/slide/SimpleSlideActivity.java

Inside the callbacks you can update your views to your liking as much as you want
