[Open Assets] Map Trails v1.3.1

Lag prevention should no longer fire instantly when joining multiplayer servers with this addon (unless the server has remained on the same map for two years).
The message displayed when lag prevention triggers is now shorter.

Implemented code to check for low FPS. If this occurs, the addon will print a chat message to whoever is dropping frames, and disable the add-on's primary functions until trail_max is changed.

Ultra mode no longer prints console debugging messages.

Fixed an issue that caused dedicated servers to record trails, but never delete them. As of this update, no server-side code will run except for the initial setting of variables.
Changed the default maximum for trails to prevent an error that happens when unpacking extremely large tables in Lua.
Changed the previous console variable (maptrails) to three different variables that control maximum number of trails, how long to wait before recording new trails, and how trails are recorded.
