Removed symlinked r10k fixture/modules directory.
Added r10k to .fixtures.yaml to allow puppetlabs_spec_helper to handle the symlinking of the module at runtime.
Added /spec/fixture/module/.gitignore to keep empty directory for testing purposes.
removed spec/fixtures exclusion from .gitignore to maintain the spec/fixtures/modules directory.
