Disable the "Report abuse" button if a user has already been reported

Hello,

I've implemented the feature request #2330. Here is what it looks like:

![report-abuse-button-disabled](https://gitlab.com/rymai/gitlab-ce/uploads/420d51906eac1c40c50701a0a340474f/report-abuse-button-disabled.png)

I hope that's an acceptable solution.

Include full path of source and target branch names in New Merge Request page

The previous title on the New Merge Request page would only show the group name. which could be confusing. Before, if you attempted to create a new merge request within the repo, it might look like this:

![image](https://gitlab.com/stanhu/gitlab-ce/uploads/d300d3a362406628ffc7c8f2b5cc6b5d/image.png)

Since they are in the same repo, this MR just simplifies this to the branches:

![image](https://gitlab.com/stanhu/gitlab-ce/uploads/5d7b3efc2399b37f84ccfd42bd5d6e8d/image.png)

However, if you create a MR from a forked project, you now see the full namespace:

Use data stored in projects instead of ci_projects

- It delegates name, path, gitlab_url, ssh_url_to_repo
- Remove ability to set this parameters using CI API

This fixes GitLab project rename, namespace change, repository rename, etc.

Add a missing RAILS_ENV=production to fix crontab clearing in the CI migration guide

All other commands in the guide set this env var, but it's missing for the `whenever --clear-crontab` call and this causes it to not clear the crontab properly.
