Common - Fixed CBA keybinds not working with progress bar

[JonBons]

When merged this pull request will:

• Due to the way the map control works we have to manually call into CBA to hook eventhandlers onto the display to work

[PabstMirror]

on current master (without this PR) I tested the following code and it worked as expected when running a progressbar

["testt", "test", "test", {
    systemChat format ["%1 - Down", time];
},
{
    systemChat format ["%1 - Up", time];
}, [47, [false, false, false]], false] call CBA_fnc_addKeybind; // v

So I'm not sure if this is needed?

@PabstMirror It only breaks with CBA binds on the numpad that are also used to move the map around in vanilla arma (Num 2/4/6/8, etc) due to the fact the cursor hack uses a map dialog.

confirmed needed for those keys
and cba_events should be able to handle the doubled events for normal keys
