Refactored board.js return.

Return condition started one line below the return keyword. It made it return undefined.
Created initial config file and initial console message.

User needs to know what to do when he sees console for the very first time.
Modified 'help' command.
Added 'commands' help page
modified 'default' and 'module' help page.

Help files are very important part of the script. They have to be as clear and descriptive as possible
Added default color to config file and set it to #c0c0c0 (same as window's console).

It should be possible to set default color via config file and window's console default color is more legible.
