Pre-release version with new local_glider_files templates

[woensug-choi]

Problems solved:

• Unsustainable absolute paths of ocean current database files
  • Now any database files in the same directory as the launch file is being searched
• Minimizes the absolute paths for files in the local_glider_files using $(dirname) in the launch files which corresponds to the current directory

Others:

• Wait time of performing initial relocation of the vehicle is changed to 1 sec from 0.01 sec for safety.
• this->model->ResetPhysicsStates(); is also included in this for trying to prevent the freezing
