#16 - Added Maven Central distribution

Introduced properties for GPG plugin and forward them to the execution of the release build. Public release versions now trigger the "central" profile being used which will enable the Nexus repository distribution.

Renamed GitCommands.checkout(…) to update(…). Made sure that project release build execution now also authenticates with Artifactory beforehand.
