Gradle Plugin - New "ALL_PUBLICATIONS" parameter

Following the discussion in #407, the _publications_ method now accepts a new parameter, "ALL_PUBLICATIONS", that will trigger the usage of all publications configured in the build script.
The parameter can currently be passed in a `build.gradle` file and used by the Artifactory Plugin directly, or be passed to the _publications_ API in Jenkins.
Other CI integrations will be supported in the future, after the _publications_ API will be implemented on their end.
