refs #8323 - Made improvements to the handling of copying and filtering of resource files.  Gradle versions of the input files have been created since they use a different token style, and the clean tasks have been configured to look for resource files, instead of just checking for a build directory.

Merged 'develop'.

refs #8323
1.  Fixed test cases that were failing

4.  Fixed description in annotation service build file
refs #8323 - Error now thrown and build stopped on unsupported environment, rather than defaulting to cdh5.
refs #8323 - Added Julia live demo support.
refs #8323 - Added ignore for generated build.properties so that it doesn't get checked in by accident.
refs #8323 - run scripts updated to include hbase jar refs based on build type.
refs #8323 - War overlays are now based on project artifacts, rather than those supplied by a maven repo.  This fixes issues with builds not being able to locate war files, as the install task runs last.
refs #8323 - Added support for gradle wrapper, and fixed an issue where the scalac call was failing in IntelliJ due to the source and test output directories being the same.
Fixed an error with the paths for the phantom-js executable that was causing tile-service builds to fail, set Gradle to run as a daemon to improve build startup times.
resf #8323 - Fixed issue with annotation unit test not removing temp folder. HBaseAnnotationIO test is now skipped by default.
