Registering COM python based components when not admin

[Roger Upole]

To register the com server for only the current user,
your base key should be
HKEY_CURRENT_USER\SOFTWARE\Classes
instead of just HKCU.

However, I don't know if this will solve your problem
or not.  The ICatRegister interface is supplied by the
system, so nobody but MS has the source code to the
RegisterClassImplCategories method.  I don't see
anything in the SDK docs indicating how it determines
whether it should write to HKCU or HKLM.
