Followed various suggestions about the Quick Help buttons

Changes suggested by CB re clickable Quick Help

CB: The text (try this) is hard-coded in the JSPs, rather than in properties file that can be internationalised
DIB: - it is in HtmlBundle.properties

CB: You have HTML links in the language files (which I've spent Â a lot of time trying to remove and avoid, because that means that translators need to know HTML. We should try to have HTML in the JSPs/tag files and language content in the language files (it's not always possible, but it's what I've been trying my hardest to get to)
DIB: - links moved  to Start JSP 

CB: We should have a leading / in front of the ?q= if we're going to use that.Â 
DIB: - done

CB: I think it would be nicer to have a hover over border around the box, with a hand, with a title "Click here to see this in action", as that would mean we could likely release without waiting for the translators. I'd rather not release something with lots of English text if translators haven't had a chance to translate it.
DIB: done - added to HtmlBundle.properties "Click to try this"
