Spotless Eclipse Framework Final (#261)

* Common Spotless Eclipse Framework which can be used by most Spotless Eclipse based formatters.

* Added usage information for fat JARs.

* Make developers in common java-publish.gradle configurable.

* Enhanced framework interfaces.
Eclipse core uses plugins not derived from Plugin but BundleActivator.
Provided possibility to configure global preferences.
Usage of Consumer allows the user to get rid of statics.

* Refactored directory structure as discussed in #234

* Refactored directory structure as discussed in #234

* Adpated package names according to previous commit. Applied fixes as requested in #234. Refactored artifact name and version as discussed in #226.

* Moved LINE_DELIMITER to SpotlessEclipseFramework

* Enhanced error report in case OSGI bundle creation fails.
This improves the development of Eclipse formatters.

* Applied review proposals.
Enhanced BundleController by creating separate class for SimpleBundel (previously called SystemBundle).
Added support for plugins offering headless builds.

* Allow configuration of snapshot repository for upload.

* Added Gradle dependency lock support.
Applied changes requested by review (@JLLeitschuh).

* Changed "unchecked" warning suppression for Java 10 compliance.

* Replaced JavaDoc @see with @code to avoid warnings when referring to implementations in dependencies.

* Added missing method implementation (org.eclipse.osgi update from 3.12 to 3.13)

* Fixed bintray usage. Plugin-ID for bintray does not work within script (see #1262).
Removed model space to allow local publishing of releases.

* Finalized version 3.0.0
