we now use an enum similar to UE4 with Fatal, Error, Warning, Display, Log, Verbose, and VeryVerbose
Log will only go to the log file unless -verbose is passed on the command line
reduced some of the output from UAT to be Log only

* Remove ErrorReporter.Error, replace with AutomationException with Error Code.
* Move ErrorCodes to AutomationException.
* Don't return exit codes. Solely rely on exceptions to propagate exit codes.
* Remove MainProc delegate
* Remove setting of Environment.ExitCode as it is ignored when main returns an int.
* ShutdownLogging is nothrow, as all exceptions would be ignored anyway.
* Wrap all shutdown steps so further ones get a chance to run.
* Move HostPlatform.Initialize into the global try/catch block

Add BuildOnlyPlatforms_MonolithicOnly to the RulesCompiler, to specify platforms that we want to compile but not cook
Add concept of "Dependent platform" to UAT, where the cooked data comes from a source platform, and is duplicated at stage time
Updated brutal submit to handle the same changes already being submitted during a build.
Brutal submit now considers it as success when it attempts to reconcile with latest in P4 and finds no files are different in its workspace.
Fix formatting on automation.cs files to avoid future integration issues, unify as tabs-as-tabs instead of spaces
