Customize fonts/colors of the "Messages" pane

[GoogleCodeExporter]

What should this feature enhancement do?

I was able to customize the colors of the query pane with a gtksourceview-2.0 
theme, but it's actually impossible to customize the color of the "error" and 
"info" messages in the "Messages" pane.

With some GTK themes these colors could become unreadable.

This pane also seems to use a different font than the one specified in the 
settings. It would be nice if every font/size setting would be customizable for 
the same reasons.

Thanks
