Support v4 jar in the project conflicts

When using your project as a gradle dependency I had some conflict issues. I forked your project and did some changes to get a provided version of support v4 library.

When I have some time I will do it properly and create a pull request, in the meantime you can check the changes here.

Thx for the awesome lib BTW.

Start by comparing this project's Gradle dependency configuration with the changes in the linked fork, focusing on how support v4 is declared. Done means the library can be consumed as a Gradle dependency without a support v4 conflict; verify that behavior with a dependent project.
