#29 @msgs should support color

[Iain E. Davis]

@messages should support color.

Currently, the work around for presenting color in an
@message or description (if using inserver look) is to
use MPI:

{ansi:^RED^text goes here}

Note that depending on compile time server options,
you may need to use:

{null:{ansi:^RED^text goes here}}

To prevent non-color copy of the text appearing as well.
