Bjørn Forsman bd01fad0ed Captialize meta.description of all packages
In line with the Nixpkgs manual.

A mechanical change, done with this command:

  find pkgs -name "*.nix" | \
      while read f; do \
          sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
      done

I manually skipped some:

* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)

longDescription = ''
The Apache Hadoop software library is a framework that allows for
the distributed processing of large data sets across clusters of
computers using a simple programming model. It is designed to
scale up from single servers to thousands of machines, each
offering local computation and storage. Rather than rely on
hardware to deliver high-avaiability, the library itself is
designed to detect and handle failures at the application layer,
so delivering a highly-availabile service on top of a cluster of
computers, each of which may be prone to failures.
