Support for new language: mojo

[BenAlheit]

Mojo is a relatively new (and, imo, very exciting) language that offers a repl experience through the terminal. I would really love to be able to use this in vim-jukit

Ps. I just realized that this works pretty much out of the box if one has mojo installed and sets
:let g:jukit_shell_cmd='mojo'
However, there is a slight quirk (from mojo's side really) that for a block of code to be run two sequential newline characters need to be sent to the repl. So, if a cell does not have a blank line at the end then the execution hangs until a blank line is sent to the repl.
