Released 1.0.0-M4-rev1

* Some advancements towards AGP 3.0.0

* Expanded Unit Test suite to run tests for 2.x & 3.x variants of the AGP

* Mark test source folders as such in IDEA

* Use default JUnit Platform version

* Performed some sweeping inside the plugin’s compile & runtime dependencies, and tasks

* JUnit 4 is included by default, which allows AS builds w/o “class not found”
* Deprecated junitVintage() dependency handler & issue a warning
* Both TestEngines are included on the runtime classpath by default
* Disable the default unit test task if JUnit 5 is used
* Some clean-up

* Moved around unit test cases for 2.x & 3.x

* Bump to 1.0.0-M4-rev1
