2.0 Lesson, string default changes needed

Short version: see post http://moodle.org/mod/forum/discuss.php?d=164368#p721630

Quick fix:

change addaquestionpage to read "Add the page"
change activitylinkname to "{$a}"
change returnto to "Go to: "

I think we can put off renaming the addaquestionpage as a $string to something else, just change the default.

Has to be an error in the lesson php code where it puts the $returnto in front of the $activitylinkedto when there is a linked to activity in Lesson settings. Not sure which file but assume view.php. Here is the screen shot I put in the forum. Of course I put "Wowie I want to go to:" to make sure I had the right string

Deleted my recreation of the add a content page where it says "add a question page". Changing the default string text seemed elegant and simple. It does not matter that the teacher know it is a question or content or end of branch page for that matter.
