Add --print-fps option to output FPS to stdout

Works both for the editor and games.

Projects can still use "debug/settings/stdout/print_fps" to enable it
permanently. The --print-fps option takes precedence (so works even if
the project setting is disabled). That setting is also no longer redefined
on the fly based on the verbose flag, that was a mess.
