Add commands attributes-display-all and attributes-display-none

[aadcg]

These commands would complement toggle-attributes-display since they would show/hide all attributes in one go without having to mark/unmark them in the prompt buffer.

Additionally, a user option could globally prevent from rendering attributes.

I like it!

@hgluka This is related to what you have been working on. While not being a top priority, it doesn't hurt to get it done while the focus is on a tangent topic.

Would we need buttons for these commands in the prompt buffer, along with toggle-attributes-display?

[aadcg]

No, that's outside of the scope right now. The commands should be bound to keys.

[hgluka]

Do you have any good suggestions for keybindings?
toggle-attributes-display is currently C-] in CUA (and Emacs) mode and z a in vi mode.
Are there any similar commands/keybindings in Emacs, for example, that we should try to replicate in the case of attributes-display-all and attributes-display-none?

[aadcg]

It could be C-shift-] and the command would toggle between hiding and showing all attributes. I have never used vi so I can't suggest a keybinding. It's ok to just bind it in the default keyscheme, from which all others inherit.
