Easier way to add a DLL to the GAC

To quickly add assemblies to the GAC - a registry key can be created
which allows you to right click the DLL and 'GAC it' in one click.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\dllfile\shell\gacutil\command]
@="c:\\windows\\Microsoft.NET\\Framework\\v1.1.4322\\gacutil.exe /i
\"%1\""
