Add last push widget to starred projects dashboard

This adds the last push widget to the starred projects dashboard. If a user set the starred projects dashboard as their preferred dashboard they would not see last push widget. The look is seamless between starred and 'your projects' dashboards.

Make Visit project on GitLab button goes to The internal Gitlab project

Since we are merging CI into CE, projects should go to the internal Projects
page, we can also use Turbolinks to do so.

In order to give the user an idea of integration, I renamed the button: "Go to
Project"

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.
