[INTERNAL] gsl-removal: fixed documentation generation
[INTERNAL] gsl-removal: removing last references to GSL
[INTERNAL] gsl-removal: adaption to restructuring of the Lib layout
[INTERNAL] gsl-removal: added Eigen and WildMagic to pyOpenMS
[INTERNAL,API] gsl-removal: fixed pyOpenMS
[INTERNAL] gsl-removal: make boost 1.47 compatible

boost::random::uniform_int_distribution -> boost::uniform_int
boost::random::random::mt19937_64 -> boost::mt19937_64
boost::random::uniform_real_distribution -> boost::uniform_real
boost::random::cauchy_distribution -> boost::cauchy_distribution
boost::random::normal_dist -> boost::normal_dist
[BUILD] remove GSL from build system
[PYOPENS] setup.py as minimal as possible

    moved codegeneration and moving of files needed for
    pyopenms distribution to new file create_cpp_extension.py

    setup.py is now as minimal as possible, which provides errors when
    using pip and its dependency resolution mechanism.
[PYOPENMS] only one build target for pyopenms

    building files for distribution + building extension "in place"
    in one step. this is faster than seperate builds, as the
    c++ compiler and linker are only called once
[PYOPENMS] refactored build targets for pyopenms
[PYOPENMS, CLEANUP] reformatted pyopenms.cmake
[NOP] added libs for travis
[INTERNAL,API] gsl-removal: removed abselut refereces to 'delta_abs_error' and 'delta_rel_error'
[TEST] gsl-removal: changed relative tolerence
[INTERNAL] gsl-removal: removed abselut references to epsilon_abs/rel
[INTERNAL] gsl-removal: added default header text
[PYOPENMS, FIX] fixed dependency decl in pyopenms.cmake
[API,FEATURE,TEST] Improved fitting of models to mass traces

- new method "getValue" to evaluate the model at a point
- more robust estimation of initial parameters for Gaussian model (caveat: fitting may use more steps in some cases)
- adapted tests
[FEATURE,PARAM] added checks for elution model validity; changed settings of OpenSWATH feature finding
[INTERNAL,TEST] increased accuracy of approximation for AUC calculation (for consistency), adapted tests
