Change keybinds with control modifier to use command on Mac

[valentinegb]

What is your request?
On Mac, most keybinds which use control as a modifier should use command.

What problem does this solve?
Many ChroMapper keybinds which use control are very strange for Mac, for example, ⌃ C, ChroMapper's copy keybind, is almost always ⌘ C on Mac. Additionally, some default keybinds cannot even be used because they conflict with system keybinds. For example, ⌃ and arrow keys, is already used by the system for Mission Control and can't be used in ChroMapper.
