[editor] Add bindkey-all function to show all bound keys (#1358)

Browse Source 
* [editor] Add bindkey-all function to show all bound keys

Function which allows you to see all the bound keys for all of
the different keymaps. It does accept arguments and passes them
through to bindkey -m "$keymap" so you could set a shortcut to
all keymaps as well if you wished.

Makes it much easier to see and grep what keys are bound to each of
the different keymaps.

When no arguments are given it will print keymap headers to stderr,
if given arguments it will not print anything extra to the screen.

* [editor] Update README to include information about bindkey-all funct.

Convenience Functions
---------------------
### bindkey-all
Provides a function `bindkey-all` which can be useful for checking how all of the
keys are bound. Normal `bindkey` command will only list the keys bound for one
keymap, which is not as useful if you want to grep through the output. The
keymap's names go to stderr so when you grep through bindkey-all's output you
will still see the headings and can tell which keymap each binding goes to.
It will also pass through arguments so you can use bindkey-all to set bindings
for all keymaps at once. If provided arguments it will *not* print out the
names of each of the keymaps, and just run the command fear each keymap.
