Patch implementing dialog

I would like to add a dialog at startup to make sure Glade users know about the survey.

This requires a string and UI break even though it wont change any screenshots.

The dialog looks something like this:
╔═════════════════════════════════════════════════════╗
║                                                     ║
║   We are conducting a user survey                   ║
║   Would you like to take it now?                    ║
║                                                     ║
║   If not, you can always find it in the Help menu.  ║
║                                                     ║
║ ▢ Do not show this dialog again                     ║
║                                      ╔════╗ ╔═════╗ ║
║                                      ║ No ║ ║ Yes ║ ║
║                                      ╚════╝ ╚═════╝ ║
╚═════════════════════════════════════════════════════╝

Once the user checks the checkbutton then the following message will be showed in the
statubar instead of the dialog.

"Go to Help -> Registration & User Survey and complete our survey!"
