FEATURE: Improved debugging view on CLI interface, by having a separate DebugView subclass that takes care of error output for this situation.
API CHANGE: Added Debug::log_errors_to(), to log errors to a file. git-svn-id: svn://svn.silverstripe.com/silverstripe/open/modules/sapphire/trunk@60368 467b73ca-7a2a-4603-9d3b-597d59a354a9
