Nautic XP alpha version revision 630

Changelist (major changes only):

• the anchor system is improved. The anchor needs now some certain distance on the ground to dig into the sea floor. Too fast and the anchor will just scrap over the ground
• AI traffic land avoidance improved (still WIP). Large ships will stop if not able to turn. If you are lucky and are in a tug boat, you can come close and request a tug task on the next harbor
• Docking panel improved. You can now select different line types with different materials, diameter and max strength (max strength not yet adjusted for every line type)
• Thrusters are activated now with shift + key and deactivated in the same way
• Thruster will build up their power based on the thruster/ship size over over a certain period of time
• dynamics for large ships put now on a realistic level. e.g until our container ship arrives at full speed ahead it might take up to 8-9 minutes
• Radar screen changed color scheme, Added AIS info panel and AIS marker on screen
  CPA warning feature added. Can be activated by right click on radar hud. shows a warning once the current travel path of ownship and any AIS target is getting close wihtin the next minutes.
• Radar AIS target can be changed by HUD radar mouse wheel
• Radar range can be changed on the HUD by left click
