Deprecation removal of Gradle GUI (#1749)

Remove Gradle GUI code, leftovers Open API code and user guides.

Removed some deprecated methods from Project and Test.

Remove @author tags and names from source code.

- Added checkstyle check for @author

- Added not to CONTRIBUTING.md saying that we don't use names in the codebase

Added several features to the output window: search, navigate to next/previous links, stop execution (without closing the tab), and add to favorites. Duplicating a Favorite now immediately puts it into edit mode. Task tree sorting is now case-insensitive.

- Incremented tooling API protocol number prior to milestone release. - Improved reporting when attempting to use an unsupported Gradle distribution via the tooling API. - Some tweaks to GradleVersion.

Switched on checkstyle rules for brace placement, and reformatted some code

Renamed subprojects/gradle-(.+) to subprojects/$1
