Double used instead of float in MySplash.
Rectangular progressbar instead of a single line.

Small mistake corrected in the height of the progress-bar and the use of
drawLine instead of fillRect.
Little adjustment.

JavaDoc slightly updated and one more pixel added (not removed actually)
to the progressbar because of the last change (drawLine to fillRect).
Little splash test along with loading structure.

Little splash test (do not forget the "-splash:splash.png" JVM argument
to test it) added.
Loading procedure for the main method roughly descripted.
