 * Sends colored message to player.  Set index to 0 to send text globally.

 *          green       ^4   ; use location color from this point forward
 *  red/blue/grey       ^3   ; use team color from this point forward

 *          normal      ^1   ; use normal color from this point forward
 *
 * The team color is defined either with a sender's index, or a specific team color using print_team_* constants (print_team_blue, print_team_red, print_team_grey).
 * A message must start with a default color.
 *
 * An example would be: client_print_color(id, print_team_red, "^4This is green ^3this is red, ^1this is your default chat text color");
 * Another with index : client_print_color(id, idOther, "^4This is green ^3this idOther's team color, ^1this is your default chat text color");
 * In multilingual file : KEY = ^1This is normal color, ^4this is green, ^1normal again ^3and now team color.
 *
 * @param index         This is the player index (1 to maxplayer) you want to send the message, use 0 to send to all players.
 * @param sender        This is the player index you want to use the team color, see print_team_* constants if you want to force a color.
 * @param fmt           Format string in which patterns gonna be replaced with argument list.
 * 
 * @return              1 if the message has been sent, 
 *                      0 if the index specified is a not connected player,
