Tests for bound properties in java.awt.Component

[Roman Kennke <roman at ontographics dot com>]

Hi,

I have made a testcase to check if the properties of java.awt.Component
do fire PropertyChangeEvents correctly. Since it is documented poorly or
plain wrong which properties are bound and which not I have taken the
JDK as reference. I started with all the properties that are present in
Java 1.2, I'll add the rest later (in seperate test cases). I attach the
testcase, please review and approve for commit.
