HFMCmd 0.4.0

• Due to differences in the type libraries between versions of HFM, different builds of HFMCmd are required for each major version of HFM, at least under .NET 3.5. [Under .NET 4.0, the introduction of the new dynamic type functionality provides a possible solution using late-binding of COM methods, but this is not yet functional in this release.]
• Added an interactive shell mode of operation; to access, just start HFMCmd without any parameters. This will drop you at a hfm> prompt, where you can then enter commands interactively.
