Small Sysdyn stuff:

Small Sysdyn stuff:
* Check if the loop exists any more in loop type determination (refs #4793).
* Added check for widget disposal to adjustable tab (refs #4793).
* Added the Playback simulation coloring profile as a default (refs #4803).
* Deleted an excess flow from an example model (refs #4793).
* Added default arrow color to Right-click -> Font... (refs #4803). This is hard coded though so changing default doesn't affect these arrows, but they must be changed manually again :(
* Updated tooltip text to Variable filter (refs #4803).
* Bugfix to SensitivityChartAxisAndVariablesTab.java (refs #4803).
* Set getOutline() in ResizeNode to protected for a future need.
