Added support for '.jar' plugins

Vigral is now able to load plugins from jar file under the following conditions:

• one jar file per algorithm
• the jar file must have the exact same name as the algorithm

For those algorithms, that uses inner classes or anonymous inner classes, you will get multiple .class files (e.g. MyAlgorithm.class, MyAlgorithm$1.class, and so on). You can Export the MyAlgorithm class as jar file, with all inner classes in it. This will lead to a cleaner plugin folder.

Further, an Error Dialog is added for identifying problems of implemented algorithms.

"2-graph-visualization"

Replaced the old graph panel by a split panel to be able to show 2 graphs simultaneously in visualization mode. That new feature can be tested by visualizing the "Push-Relabel" algorithm, that is included in this release.

CAUTION: This and further releases are compatible with java 6, to address more possible users. The older versions only work with java 7 or above!
