automatic documentation update
Cleaned up IRK example
Build system: cmake did not create python targets anymore for VC2010.
Apparently it needs the target  "python" at top level.
But this breaks the functionality of having swig/python content copied over.
This is a workaround.
Concerning #665, finally a successful compilation
Make sure unittests pass if IPOPT is not included
Added sensitivity analysis to IRK example
CLoses #673 - begone, magic collocation numbers
Obvious ommision in 2e1448c9
