ubuntu's AboutDialog template does not correctly specify the logo

[Philip Peitsch]

After creating a fresh quickly project, the About dialog causes an error to be displayed on the running command line. The error is:

/home/insanity/src/quickly/aboutboxtest2/aboutboxtest2/AboutAboutboxtest2Dialog.py:52: GtkWarning: Unknown property: GtkVBox.logo
  builder.add_from_file(ui_filename)

In the Aboutcamel_case_nameDialog.ui in the ubuntu-project template, it can be seen that template the logo is actually being specified within the GtkVBox object, rather than the parent AboutDialog where it should be.
