glassesValidator v1.2.5

• Now use median instead of mean when computing offset (acc) data quality measures. Since a fixation classifier is used that is robust to spikes in the data (I2MC), median is a better representation of the offset of the fixation intervals delivered by I2MC to the validation targets
• Fix two crashes in msgbox that pops up when an error occurs
• SeeTrue STONE importer:
  • ensure frames are in the right order also on file systems that don't provide alphabetically ordered file listings
  • removed two checks that the manufacturer said are not needed
• Hopefully make precompiled exe able to find the include ffmpeg.exe
