Added:
- Possibility for admins to send other players on a travel (similar to the existing feature for flights) => new messages
- Command "/dt rembugdragon" which removes the nearest enderdragon within a radius of 10 blocks around the player. Can be used to remove bugging stationary dragons of DragonTravel (only a temporary workaround). Enderdragons which are still recognized by DragonTravel will be removed as well, but will be respawned on next server startup. Use "/dt remstatdragon <name>" for them as usual.
Fixed:
- Some bugs in message handling for stationary dragons and added new messages
- Serious problem about quite some missing permission checks
Refactored:
- Handling of functionality "sending other players on a flight"
