New icons to commit for HighContrast-SVG

[Luca Ferretti <elle uca libero it>]

Here[1] is a screenshot of new icons I'm going to commit in the next
days (plus the version control for placeholders and some fixup to other
icons). Details for each icons will be available in
gnome-themes/ChangeLog (note that some icons are just an experiment,
such ash the theme one).

Comments? Ideas?
