fix a typo
cmake build system: parse the dune.module files of all dune modules

also, put the output variables for dune-grid into config.h
add reference solution for the adaptive 2p2c test to make jabba happy
spline test: relax tolerances a bit so that the test does not fail on dune trunk anymore with optimized gcc builds
black oil fluid system: make the methods for the properties of gas saturated oil public

also replace "flash" by "saturatedOil".
