nix needless include, less rebuild time
workaround bug in apk logic

Issue: #48

flag for raw sensor data set despite datagram with fused data only
clarify win32-joy 6 of 8 axis and remap moved to core
crop to make icon less bad
Rename HT combobox entry

Thanks @KyokushinPL for report.

Users don't seem to notice what HT does.
core: nix support for camera device identifier
use more savory UI style on win32
reorder access(2) header for clarity
adjust some UI stuff, breaks muscle memory sadly
indicate UI contains a "video feed" element
fixup! 725e9c0e6ba5d3ab1bded4f104ce03cd57d3de4b
only remove "no feed" image if tracker provides a video feed
