New Interface Design & Test Images

New:
-------
* New grouped interface design.
* New test images (in: `[root]/More Images`).
* Renamed some objects.

Important Notes:
------------------------
1.  The counting sort radio button wont work now because the function "CountingSort" in Class "countingsort" returns a variable of type "int[]" instead of "byte[]".
2.  For logical reasons, the Adaptive Median section of the program doesn't work right now.
