Done,

I've also added a comment how to use it in future versions. The idea is to 
increment the lower digit when for example new features are added to the 
featuretype enum, so that applications can check the SENSORS_API_VERSION and 
conditionally support new features for example (if they don't/can't check they 
will no longer compile against an older libsensors).

The middle digit is both an overflow for the lower, and/or for bigger changes 
like the addition of methods. I know the addition of methods would mean apps 
compiled against the new version will not work with the old, but this is quite 
normal todo, see for example gtk2 and many others.

Let me know what you think of this scheme and / or feel free to change it.

Regards,

Hans
