Nexus deploy artifacts script

Wat doet dit?

1. haalt laatste versie van package op uit nuget nexus repository
2. download nuget package & unzipt & haalt DLL file hier uit (kan 4.5 4.0 of 3.5 versie zijn)
3. kopiëert dit naar doelserver

Integraal deel van "deployen" in verband met modules, wordt bvb gebruikt in [Teamcity]({{< relref "wiki/code/build/teamcity.md" >}}) configuration
