Fachwerk 0.4.3 released

This release adds an export function to generate customized illustrations of the strut-and-tie model. Fachwerk exports the model and background to an editable Drawj2d-drawing. Various settings like colours or labelling (e.g. tension forces only) can be adjusted.The independent command line program Drawj2d then easily generates vector quality pdf, svg or emf (MS Word) graphics.

The fallback language has been set to English. Mac OS X users will notice the better visual adaption to the system, the menu bar is anchored to the top of the screen.

The way the source code is compiled and the software is packaged for distribution has been simplified. The java-based build tool Ant is used. Unused parts of the math library have been removed, thus avoiding external build dependencies. The project's source repository is self-contained, the code compiles on JDK 8 (requiring at least JDK 6). A spec file for building Linux rpm software packages is provided.
