tgfx windows x86 x64 build 3256 - Debug output files

[cmcgrath5035]

I now see output.log and error.log diagnostic files both Win7 and Linux
output.log looks like it could be useful, just starting to study

Feature request - prepend the output.log file name with date/time stamp, something like 2014-04-23_08.50.13-output.log, so logs are not overwritten in error and self document
