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.

CLooG is a free software library to generate code for scanning
Z-polyhedra. That is, it finds a code (e.g., in C, FORTRAN...) that
reaches each integral point of one or more parameterized polyhedra.
CLooG has been originally written to solve the code generation problem
for optimizing compilers based on the polytope model. Nevertheless it
is used now in various area e.g., to build control automata for
high-level synthesis or to find the best polynomial approximation of a
function. CLooG may help in any situation where scanning polyhedra
matters. While the user has full control on generated code quality,
CLooG is designed to avoid control overhead and to produce a very
effective code.
