Added loftContinuity

Added the attribute loftContinuity to wingType and fuselageType.
Currently the default behaviour in TiGL is C0 continuity for wings and C2 continuity for fuselages.
If not set, these defaults should be kept, otherwise the value of loftContinuity should be considered when lofting the component in TiGL.
