These changes are needed for Terasology to work with Gestalt DI. This is to go along with the main Terasology pull request.

It appears to do the following (although I am no longer certain of this):

• Add additional input validation to catch null beans when closing the context
• Upgrade the JavaPoet library (although I am unable to recall why by this point)
• Fixes for using array/list values as annotation parameters when inspected by Gestalt DI's annotation processor
• Change !semver.preReleaseVersion().isEmpty() to semver.preReleaseVersion().isPresent() (this may have been due to a breaking ABI change in the JSemver library)
