PATCH: [#13656] Bad rotation computing for manual rotation higher than 180 degrees

Browse Source 
By Fabrice Tiercelin

This enables rotation angles of more than 180 degrees to result in the same rotation applied to the object (the result used to be clamps between -180 - 180 of the initial rotation).

The patch had to be modified to deal with IPO keys properly
