Setting for return (enter) key to create a newline

[tadamcz]

Thanks for making this awesome plugin and open-sourcing it!

Suggestion: allow the user to select a setting that will cause Return to make a newline, and Cmd+Return to send the message. This is (IMO) much nicer for writing longer inputs.

Thank you for the feature request! Currently, newlines can be added using Shift + Return. However, there is a bug in the rendering phase.
