#51 Show only csUnit in references dialog

[Manfred Lange]

VS allows adding references to assemblies to a project. After installation via msi-file, all csUnit assemblies are displayed regardless of whether they can be used by a client application.

Basically, the csUnit.dll assembly should be in a folder separate from all other assemblies so that in the "add references" dialogbox only this single assembly appears. The other assemblies are for internal use anyways.
