Home button does not make correct url if initial task pane url has parameters

[jng]

Open a web layout with the following address:

​http://www.google.com?foo=bar

Load the web layout, inspecting the task pane will reveal the correct base url (w/ the foo=bar in the querystring)

Now hit the home button and inspect the task pane again, the url is now something similar to:

​http://www.google.com/?foo=bar?SESSION=96594330-e283-11df-8000-080027009413_en_7F0000010AFC0AFB0AFA&LOCALE=en&MAPNAME=Sheboygan

Note the double '?'. This is due to the GettingStartedURL() function in mainframe.templ naively appending the querystring to the base url without checking if the base url has query string parameters.

This function needs to be modified to take this into account.
