[cp-patches] FYI: Added headless checks to Toolkit

[Roman Kennke]

I added checks for a headless environment to Toolkit.createCustomCursor 
and Toolkit.getBestCursorSize.

        * java/awt/Toolkit.java
        (createCustomCursor): Added check for headless environment.
        (getBestCursorSize): Added check for headless environment.
