Add a button to use the content translation extension
We would like to have a campaign parameter set in the URL that is navigated from the button. For example, it can be 'articleplaceholder'.
This will allow us to configure Content translation to activate the beta feature for the user without going through special:preference and all.
Also helps us to do analytics to see how many translation started from a workflow starting here.
An example where this kind of campaign and automatic beta feature activation is implemented: http://recommend.wmflabs.org/
