Unity Build V3: Project Versioning Feature

The purpose of this update is to give users a way to have their pipeline modify a Unity project's bundle version and/or bundle codes and then check-in those changes back to the repository, potentially create a tag.

Features

• Modify project bundle code (Android)
• Push changes to repository source branch and create a tag (configurable)

This feature is now feature complete for v1 and works as intended. I will be testing for some time in my own pipelines.
