cannot remap copy to ctrl-c

Description of the problem or steps to reproduce

i wanted to use ctrl+c (no shift, just: ctrl+c) instead of the default ctrl+C (you need shift with the default keybind). so i created ~/.config/micro//bindings.json and i've put inside:

{
"ctrl-c":"Copy",
"ctrl-p":"Paste"
}

and it is not being picked up by micro.
i tried to change the case with: "Ctrl" instead of "ctrl", i also tried "Ctrlc" and "ctrlc" and more, but nothing woked.

i also tried with the nightly:
$ ./micro --version

it didn't work either.

i use that hotkey in my terminal all day long, it works fine, i copy with ctrl+c, and i send break with ctrl+shift+c. i wanted to do the same in micro.

Start by reproducing the key remapping with ~/.config/micro//bindings.json using the stated bindings and compare it with micro's key-name parsing and configuration loading. Done means that ctrl-c performs Copy in micro while ctrl-shift-c remains available for the terminal-style break behavior.
