Font colors and text output commands

[rld]

A couple related questions:

1) How many configurable font colors are there supposed to be? The message editor gives you the option to set colors from Alt+0 to Alt+6, which makes it look like there are seven, but the Configure Adventure module only provides options to set [0], [1], [2], [4], [5] and [6]. If you type '3', it sets the colors for [0]. Is there some reason [3] is missing from the list?

2) Is there any way to use one of the alternate colors when writing a value with SAYVAL, or is it limited to the standard color?

3) Is there any way to write an arbitrary character to the screen using SAYVAL or another command? For instance, writing an asterisk '*' to character location 5,5?
