Add helm-find binding

[justbur]

My proposal for #3108

Replaces SPC f l for find-file-literally. If that's a useful binding then maybe we can move this. I like fl for find "locally" and fL for find "globally" on the system.

Do you think adding documentation about installing find (and locate, while we're at it) on Windows is necessary? I don't use Emacs on Windows, so I don't know if it's really needed.

[justbur]

Yes that would be nice. I can put it together

Added note to windows users

I was the one who suggested find literally, it's extremely useful to get around emacs' slow long line rendering for really big files, but it is niche enough to move I guess. "f C-l" or "F l" come to mind, any better options?

[justbur]

@sooheon This is a different approach, but wouldn't it makes sense to add a helm action for helm-find-files that allows you to open it using find-file-literally?

[sooheon]

@justbur that way does seem more elegant :)

[justbur]

@sooheon try this

(helm-add-action-to-source "Find File Literally" 'find-file-literally helm-source-find-files 2)

[sooheon]

@justbur yep thanks. And if anyone reading uses swiper/ivy, the following is the equivalent:

(ivy-set-actions
     'counsel-find-file
     '(("l" find-file-literally "Find file literally")))

[justbur]

Great. Added the helm action to this pr
