Work Progress - Nov 3 - Nov 9

Web demo: here

Work done:
* To adjust the visibility/editability of automatable properties, two additional annotations are introduced.
-- DesignTimeBehavior: It determines where an automatable property shows up in the property window at the bottom right. "B": show up in Basic tab of the property window, "A": show up in Advanced tab of the property window, "H": hidden. Default is "B".
-- RunTimeBehavior: It decides the editability and visibility in the Expression tab on the left. "E": editable (R+W), "R": read only, "H" - hidden. Default is "E". (Note: The Core infrastructure to differentiate "E" and "R" is yet done.)
-- Example usage:
@AutomatableProperty(name="mass", desc="mass", DesignTimeBehavior="A", RunTimeBehavior="H")
public float m_mass = 1.0f;
* Bug fix on "Detaching codelet from an event with only one child creates a java exception".
* Lighter background, darker lines
* Thickness of lines is now an advanced property of the line.
* Use of annotation to indicate the naming convention (the default name of the newly created object) and class description (descriptive text shown in the new object creation dialog).
-- Example usage:
@AutomatableClass(name="SkateBoarder", desc="Skateboarder")
public class SkateBoarder extends PObjectJBox2d {
