Added the org_name and repo_name parameters to the call to action.html to pass along the repo's name and its org to variables in Team City. Without them, the TC job does not know what repo to clone unless the repo is hardcoded into the job's configuration. This change allows others to more easily tie multiple GitHub repos to a single TeamCity job. By passing the organization and repository name that kicked off the job, we can dynamically clone the correct source repository which triggered the job. This change works for both GitHub and GitHub Enterprise.
