Mike Fricker e85564743c [INTEGRATE] Unreal Build Tool: Adaptive unity builds (experimental!) ...

- New UBT support for "adaptive unity builds", which can greatly increase iterative compile times
- This feature allows UBT to keep track of which source files you're currently editing between runs
- UBT will exclude your "working set" source files from all unity blob files, allowing for fast iterative compiles!
- Currently, adaptive unity builds relies on files being writable vs. read-only to determine what you're working on (P4 edit)
- Enable this new feature in your BuildConfiguration.xml file.

    <BuildConfiguration>
           <bUseAdaptiveUnityBuild>true</bUseAdaptiveUnityBuild>
    </BuildConfiguration>
