It's not necessary to label a link with 'click', it being
a link and being formatted as such is enough.
This updates the occurences in the sytem preferences editor.
To test:
* Go to system preferences like OpacUserCSS that allow editing
in a textarea
* Verify link descrptions for editing and collapsing the area
* For a section of grouped system preferences, hover over the
arrow and verify the text for collapsing/uncollapsing the area
* Apply patch, restart all
* Verify the links and tool tips have been updated
