Notifications: subscribe link overlaps course element title

There's a problem with absolute positioning of the subscribe link for notifications. This link may overlap long course element titles (1. screenshot). While investigating this behavior, I noticed that the link <div> is not an element of <h3>, but of the content block. If the link <div> should reside on the top of the page, it should be a child of the page header <h3>. I think, this is a suggestion for future plans, because more code rewriting has do be done.

I implemented a more quick & dirty solution (2. screenshot). It also positions the help icon for notifications to the end of the link. In the actual code it is located before the link and is positioned behind the link by CSS.

Have a look at the patch, what I've done
