Pull request overview

This PR adjusts the functional-test Gradle resolution rules so functional test apps don’t get their Sitemesh dependencies silently downgraded by a stale published grails-bom snapshot, which can lead to unresolvable coordinates (notably for spring-webmvc-sitemesh).

Changes:

• Reads bomDependencyVersions from the locally-evaluated :grails-bom project.
• Adds a resolutionStrategy.eachDependency rule to force org.sitemesh module versions to the locally-defined BOM values when applicable.
