WLP: Active WLP window makes Octave-script run without progress

[hhgs]

If an Octave-script is started while a WLP window is active, the Octave process runs without any progress. If a 3D-view is set active later, any new Octave process will also fail. Same behaviour for version 1.5.0 and 1.5.109-RC.

Last active 3D-view should be used for a Octave process, when not given explicitly.

Some of the Octave commands are not robust if no Eclipse views are open, and the external procces seems to be running without anything happening. If this situation occurs, the Stop button of the Process Monitor must be clicked in order to shut down the external process.
