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.

longDescription =
'' GNU libextractor is a library used to extract meta-data from files
of arbitrary type. It is designed to use helper-libraries to perform
the actual extraction, and to be trivially extendable by linking
against external extractors for additional file types.
The goal is to provide developers of file-sharing networks or
WWW-indexing bots with a universal library to obtain simple keywords
to match against queries. libextractor contains a shell-command
extract that, similar to the well-known file command, can extract
meta-data from a file an print the results to stdout.
Currently, libextractor supports the following formats: HTML, PDF,
PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI,
MAN, FLAC, MP3 (ID3v1 and ID3v2), NSF(E) (NES music), SID (C64
music), OGG, WAV, EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ),
ZIP, ELF, S3M (Scream Tracker 3), XM (eXtended Module), IT (Impulse
Tracker), FLV, REAL, RIFF (AVI), MPEG, QT and ASF. Also, various
additional MIME types are detected.
