Cmd button in MacOS should be usable as Ctrl

[vivid-pixel]

A little quality of life improvement for the Mac users out there.

Describe the bug
The typical Windows or Linux shortcuts for copying, cutting, pasting, or selecting all would be using the Ctrl key plus C, X, V, or A. On MacOS, this is typically done with the Cmd key, but that is not interpreted by QB64. This includes Cmd-S for saving, which pops up a dialog, "Unable to save current window contents."

It's a hard habit to break using Cmd on a Mac, so one ends up accidentally replacing code with a letter "c" or "x" and then having to remember it's Ctrl-Z to undo, rather than Cmd-Z.

To Reproduce
Steps to reproduce the behavior:

1. Open a file.
2. Try to use copy and paste, or saving, with typical MacOS keys.

Expected behavior
Cmd button should be usable as Ctrl on MacOS.

Computer:

• MacOS Sonoma 14.4.1 (23E224)
• 2022 M2 MacBook Air
