(IMPORTANT! read description) Merge pull request #166 from informatik-ag-ngl/f/clearable_textfield

Implemented ClearableTextField and redesigned UI.
TAKE CARE:
in order to use SceneBuilder further, you have to import the attached
JAR "CustomComponents.jar" into the SceneBuilder. If you don't do this,
Scenebuilder no longer can load FXML files that depend on a custom
component. If you are implementing another custom component, feel free
to add it to the jar.
Note however that SceneBuilder cannot load any components that rely on
libraries other than the standard Java library or the JavaFX standard.
Meaning that even if you are referencing another Envoy file, the
component will not be importable. Because of this, the
ClearableTextField is also present only in a slimmed down version, as
SceneBuilder additionally has problems when dealing with loading
resources.
