::! and :r! support?

[acrosby]

I know this isn't being actively developed, but if someone takes it on again vim-like shelling out support with :! <command> and :r! <command> would be a nice addition.

This could be implemented for instance by just passing the command to spawn a new process. @acrosby What is :r! exactly? Can you link to some vim docs? :)

[acrosby]

:r! is just like :! but returns the command that follows it to the text buffer if there is stdin or stout.

Here is an overview that I found by googling that describes this behavior.

@acrosby Thanks for this, I have taken notes.

+1 for this enhancement.
