Wrong export name in GlyphPreview.py

[Mark2Mark]

I think that should be GlyphPreview instead of GlyphView:

GlyphsSDK/ObjectWrapper/GlyphsApp/UI/GlyphPreview.py

Line 5 in 8d3fcc8

__all__ = ["GlyphView"]

---

Also maybe add some documentation of how to import it properly.

I could not make it work neither of these imports from GlyphsApp import * or from GlyphsApp.plugins import *, so I just added the entire GlyphPreview.py to my plugin and import that one.

The from objectsGS import GlyphPreview from the file’s sample code does not work.
