Turn off tabs opening by default when viewing content

[hutchibw]

Currently, navigating to any sort of content causes a new tab to open by default. This is not a big problem, but from here, if a user doesn't close the original tab on their own and navigates to other pages from the content page then the browser quickly fills with lots of tabs. Since most users that want to open something in a new tab know how to do so on their own, it might be a good idea to change the links to video content etc. so that it doesn't open a tab by default.
