Command + C not only copies but also prints `ã` character (MacOS with Cocoa)

[barracuda156]

@arakiken This is a minor issue but quite annoying, since copying anything requires then to delete an unneeded character. Do you know why this may be happening in Cocoa? Pasting works as expected.

Mlterm copies text immediately to the clipboard after selecting it.
Therefore, pressing Command+c has no effect.
You can change this behavior by setting ~/.mlterm/main as follows.

change_selection_immediately=false

With this setting, even if you select an area on the screen, the selected text will not be copied to the clipboard until you press Shift+Control+c.
You can also change this shortcut key to Command+c by setting ~/.mlterm/key as follows.

Command+c=COPY_CLIPBOARD

In addition, I have changed the default value of COPY_CLIPBOARD shortcut on MacOSX from Shift+Control+c to Command+c in this commit.

So setting ~/.mlterm/key will no longer be necessary from the next version.
