Update boot.lua
Removing the alpha variable allows anyone who overwrote the setColor function to see errorhandler's print.
e.g. I'm overwriting the setColor function to accommodate 0-255 values and the error message is being printed with 1/255 alpha (invisible).
Removing the 1 will print the message in black.
P.S. I'm currently overwriting errorhandler for this, but I assume others are also overwriting setColor and see no error messages.
