Boeing-specific build.gradle files and associated custom Eclipse config

[pacphi]

Gradle build config at Boeing is a little more involved. They do not want to use Artifactory Gradle plugin (https://www.jfrog.com/confluence/display/RTF/Gradle+Artifactory+Plugin), opting instead for groovy task def. Shawn Karr has been able to plow through some artifact resolution issues we were having with certain dependencies and plugins by a) working with Artifactory admin team and b) by crafting a build.gradle, gradle.properties and associated Eclipse config. Want to get this into a new boeing branch.

Didn't add Eclipse config. But did resolve this along wth commit for issue #6. Commits are on a boeing branch.
