Add chat message broadcast feature

Based on an earlier patch worked on by aciidz and bill, but I found an
easier way to do it, with less asm-searching for internal stuff.

+ * characters embedded to set colors. A control character must be at the start
+ * of the string to use any subsequent ones. \x02 (STX) only works at the start
+ * of the string, and precludes using the other control characters.
+ *
+ * The list of possible control characters is as follows:
+ * - \x02 (STX) - Use team color up to the end of the player name
+ * - \x03 (ETX) - Use team color from this point forward
+ * - \x04 (EOT) - Use location color from this point forward
+ * - \x05 (ENQ) - Use achievement color from this point forward
+ * - \x01 (SOH) - Use normal color from this point forward
