for consistency with other interface classes

    t = re.sub(r'(\W)(Simulation)(\W)', r'\1I\2\3', t)
    t = re.sub(r'(/)I(Simulation)', r'\1\2', t)

(to simplify; 2 flavors are enough)

Hasn't been used since long; didn't cover FFCatalog:
there is little or no advantage in running Latex and
related commands through 'make'.

- Documentation can now be built by command 'make doxyuser'
- configured doxy files now in build/doxygen (no longer under version
  control)
- html output now under html/build

This resolves issue http://apps.jcns.fz-juelich.de/redmine/issues/2385

- rename flag BORNAGAIN_RELEASE -> BORNAGAIN_CONFIGURE_DOXY
- write configured Doxyfiles to auto/Doxygen

* Make names more uniform: FormFactorRipple1* where *=Box,Gauss,Lorentz
* Implementation through inheritance from ProfileRipple1
* Form factor in elongation direction x computed in namespace ripples

adapt GUI to change of FormFactorDot argument
