Detached configurations support

[jk1]

Consider the following dynamic pattern:

task unpackDeps << {
   def (notation, closure) = tc("${buildTypeID}:${buildNumber}:${artifact}")
   def dependency = dependencies.create(notation, closure)
   def configuration = configurations.detachedConfiguration(dependency)
   def zipFile = configuration.resolvedConfiguration.firstLevelModuleDependencies.first().getAllModuleArtifacts().first().getFile()
   unzip(zipFile.getAbsolutePath(), targetFolder, 1)
}

Build pinning, tagging and dynamic version resolution don't work, as all these actions are performed in project#afterEvaluate callback. The artifact itself still can be resolved though.
