Title: Updated all CorePlot specs

This is follow-up from CocoaPods/Specs#7383

- Changed URLs to reflect project's move to GitHub.
- Replace pre_install hook with prepare_command where appropriate (avoid deprecation warnings).
- Generally made spec file consistent among versions.

I tested these with a dummy project with a one line Podfile, they all installed correctly and the installed source files looked in order.
