Add support for installing uncompressed files during update installation.

* In addition to creating symlinks and installing files from .zip packages, support
   copying uncompressed files from the root of the package directory to the installation
   path.

   This is required for installing new versions of the updater itself which is downloaded
   uncompressed to the package installation directory.

 * Replace use of File.absolute_path with File.expand_path for compatibility with Ruby 1.8.7

 * Modify updater test to test installation of the updater binary to the install directory.
