Colorized text in the Console

Transferred from internal JIRA issue originally created 2020-07-30.

While the console is functional, it would be more user-friendly if the log messages in the Console pane were colored based on their error/warning/info status. This would be more similar to how the messages appear in a terminal when you run SUSHI/GoFSH. Typically, the "error"/"warn"/"info" words are colorized and the box with the SUSHI/GoFSH results is colorized.
