Fix podspec in Podfile with no options.

Added specs to test podspec method inside Podfile. Specs for the
default, no options version; the :name version and the :path
version.

I have added two fixture podspecs (`1st.podspec` and `2nd.podspec`) to test the default option, and the name and path options. There is already a couple of podspecs in the fixture directories, so if someone wants me to use a couple of those, instead of adding two new ones, just ask.

Should fix #708
