* Removed selectVersion. There's no good reason to write

`selectVersion ./foo "bar"' instead of `import ./foo/bar.nix'.
* Replaced `with args' with formal function arguments in several
  packages.
* Renamed several files to `default.nix'.  As a general rule, version
  numbers should only be included in the filename when there is a
  reason to keep multiple versions of a package in Nixpkgs.
  Otherwise, it just makes it harder to update the package.
