Ability to apply resizing to head group
This will help the user save time as they now have the option to apply the resizing to an entire head group instead of individually resizing a persons head throughout the video.
Click on an auto detected head
Select the option to "Resize head group" from the "more menu"
Once the option is selected, the resizing will be applied to the head group which is highlighted on the right hand panel when the user clicks on the auto detected head.
Timeline now shows all 3 digits of milliseconds
