Refactor Gradle script naming and organization

- inline test-mvc and tiles3 .gradle files for clarity
 - rename merge-dist.gradle to merge-artifacts.gradle
 - polish Javadoc for merge-artifacts.gradle
 - move merge-artifacts.gradle into gradle subdirectory
 - move publish-maven.gradle into gradle subdirectory
