* fixed some typos

Update v0.3

* New feature: Player Checkpoint Markers (Race mode menu)
- when this mode is switched on each player leaves a marker on each checkpoint as they pass through
- each marker has a different colour or pattern for each player to help tell which checkpoints they've been through
- markers reset for each player when they finish each lap
- this feature is switched ON by default

* New feature: "Mine-Point" mode - aka checkpoint mines! (Race mode menu)
- when this mode is switched on each player leaves an explosive MINE on each checkpoint as they pass through
- mines stay there even when hit and build up lap after lap
- each player's mines only disappear once they finish the race
- this feature is OFF by default

* New feature: Teleport to start (Race mode menu - if a track exists)
- when a track has been created or loaded the "Teleport to Start" button becomes available
- while not in a vehicle pressing the button will instantly teleport the player to a random point just near the start line of the current track
- in future we hope to be able to teleport the player's vehicle as well (not currently possible in mods)

* Overwriting existing track files is now permitted

* Other small bug fixes and cosmetic tweaks

v0.3 KNOWN ISSUES

* Player checkpoint markers and mine triggers sometimes partially collide with vehicle wheels and the player character. This is a TrailMakers bug affecting mods.

* Some workshop 'map mods' may cause the loaded Trailmakers base level to show as "unknown" (eg Desolate Dunes). Use the select level button if you wish to manually set the level (optional).
