Qt: Add Colorize Conversation menu items.

Add the "View→Colorize Conversation" menu similar to the GTK+ UI. Add
the "Reset" item under the "Colorize Conversation" menu instead of the
top-level "View" menu. Make sure the "Reset" shortcut is Ctrl+Space even
on OS X. Normally Qt would convert it to Cmd+Space, but that's used by
Spotlight.

Add StockIcon::colorIcon and use it to create filled square icons.
