Ready repository for release process

This commit modifies the behavior of the Rake task to use the tagged
version as the version of the repository/gem.  This will allow for
autobuilding in the future.  This is extremely similar to the heira
Rakefile and tasks.

Also got rid of a package_task warning in the Rakefile.

I also tagged the original commit at v0.0.0 to ensure this process would
work.

Fail if a lookup key isn't passed

Hiera should raise a parse error if a lookup key isn't passed.
Add test coverage for hiera_hash()

The previous commit raised a ParseError if hiera was called without a
default parameter argument. This commit adds test coverage for this
feature and updates the existing spec files to use the spec_helper
library.
(#12037) hiera-puppet should support hash values.

Puppet support hashes, so hiera-puppet backend should also support hash
values.

(#14124) Load rake tasks directly to fix tests for Ruby 1.9.x

The way we loaded rake tasks was not compatible with Ruby 1.9.x, as it relied
on the fact that Ruby 1.8.x included . in its load path. This patch loads our
rake tasks directly instead.

(#14461) Remove Puppet parser functions

The next release of Hiera will ship with the Puppet parser functions:
hiera, hiera_hash, hiera_array, and hiera_include. To prevent conflicts
the Puppet parser functions are being removed from the hiera-puppet gem.

We only provide a puppet hiera backend as described in the README.

Add mac packaging to hiera-puppet

Move conf to ext directory

Because the conf directory does not hold configuration information and in fact
holds packaging information, this commit moves the conf directory to the ext
directory, where packaging files make sense.
