disable stats

currently, we're using the cleanflight google analytics tracking id, but i dont think we want to send stats to some place we have no permission to view them :)

this has bugged me for a long time, but i don't think it's cool 1 person can see everyones hardware uuids. (also feature usage, computer properties, etc.) if we value privacy, we should merge this. alternatively, making these stats public would be fine as well.

i usually just remove the google analytics permission from my local copy, but this should fixup the issue for everyone.

if we do ever want (hopefully open) analytics, just git revert this commit and update the ga tracking id.

this is super easy to revert, so i suggest we merge and revert if/when we want to bring it back, to avoid sending any unnecessary data to google w/ the cleanflight tracking id in the time being

Yes, merge it. It is of no use at the moment and when the need for analytics arise we can revert this then.

ok, merging
