Windmaster 4.10.6

WindMaster 4.10.6 with the following features and error corrections compared to 4.10.5:

• Pibal balloons are now shown in the wind graphs if either "show all APRS object" is checked or if the pibal sending stations are checked in the callsign translation window.
• Fixing faulty calculated vertical velocity. The velocity was about half of what it should be. This fault did also affect the "snake" (Key S)
• Remove support for barometric altitude and transient filtering
