#123 *F* Fix for call to hhc that might fail

[Olivier Sannier]

Hi,

The current method of calling HHC may fail when the
path where it is located contains spaces. Typically, it
won't work when located in c:\program files.
Further to this, CreateProcess should not be called
with its first parameter set to nil, it's not reliable
this way.
The attached fix will correct this and ensure HHC is
called correctly.
