Selendroid 0.13.0

[Dominik Dary]

Hello,

version 0.13.0 was released today.

All release notes: https://github.com/selendroid/selendroid/releases/tag/0.13.0

Download: https://github.com/selendroid/selendroid/releases/download/0.13.0/selendroid-standalone-0.13.0-with-dependencies.jar

There are a lot of refactorings and new features. The biggest ones are:
- Introduced package per component. E.g. client bindings are located in io.selendroid.client
- Removed Gson dependency from server and client

Thank you for all contributions!
