We need to enhance FluidShell to support a JavaScript and MongoShell CLI.  These are the things we need to do :

1. In ShellLineInterpreter we need to add an option for "CLI_SHELL_LINE_EXECUTE_SQL_AS_JAVASCRIPT" = true | false : default = false
2. In ShellLineInterpreter we need to add an option for "CLI_SHELL_LINE_EXECUTE_JAVASCRIPT_IMMEDIATELY" = true | false : default = false
3. In ShellLineInterpreter we need to add an option for "CLI_SHELL_LINE_JAVASCRIPT_API" = aqua | mongo : default = aqua
4. The "cli" command should add options "javascript" and "mongoshell" so we can do a "cli javascript" and "cli mongoshell".
5. ShellLineInterpreter.interpretLine() we need to add a type of JAVASCRIPT_CMD
6. In CommandLineInterpreter line 1278 we need to add code to execute JAVASCRIPT_CMD
7. You can see how to execute the JavaScript engine for the aqua api in ScriptorPanel.executeScript()
8. In the Schema Tree server right mouse click menu we need to add an item "Mongo Shell" if the server is a MongoDB server.  This will open a FluidShell with the "cli mongoshell".
