Dear developers,

I would like to inform that according to the general rule or practice, pressing the <Enter> key in the textarea of the mh2 Shoutbox should just lead to the insertion of a new line rather than the instant submission of the shout message (as if the "Shout it out" button has been clicked).

This is important because the user needs to use the <Enter> key to create paragraphs and/or blank lines.

Thanks Mick!  Making it an option seems to be the most desirable or logical solution.  I hope that the upgrade will preserve all the settings and configurations already created by the user or administrator.
