Feature request: ACE vim commands

[mlopezgva]

Having vim key bindings is handy.
However, if you use ACE within Cloud9, you'll see that it has support for some basic "command-mode" commands like :w :q and a few more. ACE detects it when in "vim-mode", but they're not recognized (you can try it in zed / atom / etc by hitting : in "normal mode" while using vim key bindings).

Would it be possible to get them up and running?
