Customizable tooltips for widget properties

[ptziegler]

The way tooltips are currently implemented is by simply showing the JavaDoc. This has two major problems:

(I) Those tooltips are not translatable and will always show the language the documentation was written in.

(II) Those tooltips are only shown when the JavaDoc is part of the classpath. If WindowBuilder is used with an JRE that doesn't contain the documentation, those tooltips are not show.

There should be a way to contribute your own tooltips and then use the JavaDoc as a fallback mechanism.
