client: Add color modifiers to NEW, CHG and DEL events.

Events like [NEW], [CHG] and [DEL] can appear in the command console at
any time, even when the user is typing a command. The last line is kept
making the event line appear just before it, something that can be
unnoticed. This patch add meaningful colors for those three event to make
it easier to see them.
