Fixed Issue 341: JNI Global Reference in native code prevents clean applet termination

Simplified the native code in JAWT_DrawingSurfaceInfo.c to only
fabricate the direct ByteBuffer wrapping the JAWT "platformInfo"
struct, moving the construction of the wrapping JAWT_PlatformInfo up
to Java.

Verified fix with reloading of JOGL applets via the new JNLP applet
launching support in the new Java Plug-In.
