Add support for safe navigation operator

[elpete]

It looks like the safe navigation operator (?.) is being interpreted as a ternary operator. This causes some code breakage.

Config: default

Source:

component {

    function functionCallWithSafeNavigationOperator() {
        return getFoo()?.getBar();
    }

    function structWithSafeNavigationOperator() {
        return variables?.foo?.bar;
    }

}

Current Output:

component {

    function functionCallWithSafeNavigationOperator() {
        return getFoo() ? .getBar();
    }

    function structWithSafeNavigationOperator() {
        return variables ? .foo ? .bar;
    }

}

Actually, it looks like Lucee still parses this correctly. I'm surprised. However, I don't think that's the aesthetic we want since it looks like a ternary this way.

Thanks! I didn't have any syntax highlighting support for the safe navigation operator in place.
