Fix incompatibility between basic_gal (which used angles in degrees in rotation) and other gal layers (which used radians in rotation). Rotation angles are now in radians. 

Fix erroneous optimization in VECTOR2<T>::Rotate (which was made for angles in degrees): Angles are in radians, and only 0 rd rotation is skipped ( case very frequent, especially in eeschema)
