WindMaster 4.10.5

WindMaster 4.10.5 with the following features and error corrections compared to 4.10.4:

• Limit for creating waypoints with left click on the map is changed from 1:1000 to 1:5000. This limit also matches the limit when to call a position unreliable
• Adding checks that pibal-data exists and that elevation >0. This could otherwise case dead-lock or run-time error
• Minimum size of waypoints without radius is changed to 1 pixel. This caused some problem together with the PZ list "Hungary, Worlds PZ 2010-09-28.wrz"
• Connected PZ with radius>0 are also displayed in altitude chart. This is used by "Hungary, Worlds PZ 2010-10-02.wrz"
