[HarfBuzz] Harfbuzz 1.0.1 win32 build.

[Tom Hindle]

Hi,

Previously I have been testing with harfbuzz-0.9.27-win32 and I just 
tried harfbuzz-1.0.1-win32.

I noticed two possible defects:

1.  hg-view.exe depends on libharfbuzz-1.dll but zip file contains: 
libharfbuzz-0.dll
Renaming to libharfbuzz-1.dll (along with the .def file) made things work.

2. hb-view.exe no longer seems to support uniscribe shaper (the 
--shaper=uniscribe option)
This option was really useful to me allowing seeing the difference 
between default shaper and uniscribe shaper.

Thanks
Tom
