Implement a simple benchmarking mode which logs FPS to a file Very useful to compare performance between two builds, check the impact of a configuration option, etc. FPS log is stored in User/Logs/fps.txt and is reset each time you launch a game. Only enabled if you check the "Log FPS to file" option in your graphics settings. Could be improved a bit: currently logs only every 1s (so you can't really see small variations), maybe output more infos to the fps.txt like average/stddev (but Excel/Libreoffice/Google Docs can compute that easily too).

FPS counter cleanup - Isolate it into it's own namespace - Shorten function names, the namespace self-documents. - Just use the std I/O, we can just write directly to the stream for logging.
