Update recheck and discard old dependencies

[beatngu13]

recheck now contains all necessary dependencies from both retest-model and retest-sut-api, while I'm working on a new release of surili-commons (formerly surili-model). As soon as this is done, you should be able to go from this:

libraryDependencies += "de.retest" % "surili-model" % "0.1.0-SNAPSHOT" % "provided" withSources () withJavadoc ()
libraryDependencies += "de.retest" % "retest-sut-api" % "3.2.0" % "provided" withSources () withJavadoc ()

To this:

libraryDependencies += "de.retest" % "surili-commons" % "0.1.0" % "provided" withSources () withJavadoc ()
