- Started moving the code that turns ProjectPackagingSettings into BuildCookRun commandline from editor to C# so that we can run scripts without needing to bake out the commandline
- Updated ExecuteBuild to handle some new variables and such (like the new one for importing ProjectPackagingSettings into the commandline dynamically)
- Added ability to update a Default config file in C# (with limited functionality - set value and add array entry, with an enum we can extend later)
- Minor cleanup here and there
