Replacing old mdp entry 'nstxtcout' by 'nstxout-compressed'

NOTE 1 [file grompp.mdp]:
  The group cutoff scheme is deprecated since GROMACS 5.0 and will be
  removed in a future release when all interaction forms are supported for
  the verlet scheme. The verlet scheme already scales better, and it is
  compatible with GPUs and other accelerators.


NOTE 2 [file grompp.mdp]:
  leapfrog does not yet support Nose-Hoover chains, nhchainlength reset to 1


NOTE 3 [file grompp.mdp]:
  You have selected user tables with dispersion correction, the dispersion
  will be corrected to -C6/r^6 beyond rvdw_switch (the tabulated
  interaction between rvdw_switch and rvdw will not be double counted).
  Make sure that you really want dispersion correction to -C6/r^6.

Setting the LD random seed to -1857465714
Generated 0 of the 3 non-bonded parameter combinations
Excluding 3 bonded neighbours molecule type 'UNK'
Number of degrees of freedom in T-Coupling group System is 15432.00

GROMACS reminds you: "It all works because Avogadro's number is closer to infinity than to 10." (Ralph Baierlein)
