Fixed a regression where unescaped new line characters appeared between the "scored by" and "assisted by" messages when a player captured a flag or skull.

As a result of f0de15ad1df0, unescaped new line characters that separated the "scored by" and "assisted by" messages, and previously depended on V_ColorizeString to convert them into their escaped counterparts, remained unescaped and were now visible in the HUD message.

A simple fix was to use escaped new line characters in the strings instead, which should've been that way in the first place.
