Code style with Checkstyle

TUM Campus App employs Checkstyle in its Gradle build as an additional task.

Normally, under Gradle documentation, checkstyle plugin should autogenerate tasks, but apparently that's not the case because of Gradle Android plugin.

Task description in Gradle build file can be found here. It is important for Continuous Integration workers that an XML report is generated in specified location.

The checkstyle configuration itself can be found here. It is a copy of Android okhttp checkstyle.xml with some alterations.
