Time Attack Pace Comparision v1.1

- Updated the script to use modeattacking instead of a custom function to check for record attack
- Fixed a bug in 2.2.11 that broke the script when directly jumping into singleplayer.
- Added the singleplayer_posts console variable that handles if starposts in singleplayer/marathon mode should trigger the script. For 2.2.11 and earlier the default value is No while newer versions will default to Yes
