[PATCH] Use different colors for different message types.

[David Shea]

This is how the GtkInfoBar we have used to work, but at some point the
gnome-themes developers decided that they didn't like that anymore. See
https://bugzilla.gnome.org/show_bug.cgi?id=704266. The white-on-blue bar
is kind of terrible to read, anaconda uses the warning and error colors
to attract attention to warnings and errors, so this style change undoes
the color changes and makes the infobar colors jarring again.
