Monocle in 8u25

I managed to run Monocle/Headless on Windows with 8u25. This will allow
users to run headless tests.

All what is needed is to copy all files from "com/sun/glass/ui/monocle" of
"" and add the
cursor resource files from
"modules/graphics/src/main/resources/com/sun/glass/ui/monocle" of the
related hg tag in the OpenJFX repository [1].

Before Application#launch() is called we need to manually set the Glass and
Monocle platforms:

accessStaticField(, "instance",

The directory structure in 8u40 is a bit different, but there could be
added version checks. Checking
for the JVM vars "glass.platform" and "monocle.platform" might be also
added to this code.
