Code review comment for lp:~gary-lasker/software-center/fix-lp1023777-for-5.2

Thanks for the branch and for noticing this bugreport. The original report was against quantal and there its
easy to reproduce, the bugtitle says:
 Title: software-center crashed with AttributeError in _on_show_exhibits(): 'FeaturedExhibit' object has no attribute 'click_url'

and indeed, the FeaturedExibit lacks this attribute, so adding it there via the approach below looks cleaner to me:

to test you can use trunk or 5.2 and run:
 $ SOFTWARE_CENTER_DISTRO_CODENAME=no-real-distro ./software-center
and click on the FeaturedExhibits banner to trigger both the original bug and the fix.

As this almost caused a regression in stable I added a regression test in trunk:
 lp:~mvo/software-center/fix-lp1023777

Should be easy to cherry pick this to 5.2 too.
