Bjørn Forsman c9baba9212 Fix many package descriptions
(My OCD kicked in today...)

Remove repeated package names, capitalize first word, remove trailing
periods and move overlong descriptions to longDescription.

I also simplified some descriptions as well, when they were particularly
long or technical, often based on Arch Linux' package descriptions.

I've tried to stay away from generated expressions (and I think I
succeeded).

Some specifics worth mentioning:
 * cron, has "Vixie Cron" in its description. The "Vixie" part is not
   mentioned anywhere else. I kept it in a parenthesis at the end of the
   description.

 * ctags description started with "Exuberant Ctags ...", and the
   "exuberant" part is not mentioned elsewhere. Kept it in a parenthesis
   at the end of description.

 * nix has the description "The Nix Deployment System". Since that
   doesn't really say much what it is/does (especially after removing
   the package name!), I changed that to "Powerful package manager that
   makes package management reliable and reproducible" (borrowed from
   nixos.org).

 * Tons of "GNU Foo, Foo is a [the important bits]" descriptions
   is changed to just [the important bits]. If the package name doesn't
   contain GNU I don't think it's needed to say it in the description
   either.

GROMACS is a versatile package to perform molecular dynamics,
i.e. simulate the Newtonian equations of motion for systems
with hundreds to millions of particles.
It is primarily designed for biochemical molecules like
proteins, lipids and nucleic acids that have a lot of
complicated bonded interactions, but since GROMACS is
extremely fast at calculating the nonbonded interactions (that
usually dominate simulations) many groups are also using it
for research on non-biological systems, e.g. polymers.
GROMACS supports all the usual algorithms you expect from a
modern molecular dynamics implementation, (check the online
reference or manual for details), but there are also quite a
few features that make it stand out from the competition.
See: http://www.gromacs.org/About_Gromacs for details.
