support for simple Array type

[aidinabedi]

Fixes support for jsdoc's standalone Array keyword as can be seen in examples such as:

/**
 * Returns the sum of a and b
 * @param {number} a
 * @param {number} b
 * @param {boolean} retArr If set to true, the function will return an array
 * @returns {(number|Array)} Sum of a and b or an array that contains a, b and the sum of a and b.
 */
function sum(a, b, retArr) {
    if (retArr) {
        return [a, b, a + b];
    }
    return a + b;
}

Without this PR, tsd-jsdoc will generate invalid typescript (because outputting just Array will conflict with the built-in generic interface Array<T> ).

Not sure the output you want is simpleArray: []; because that is semantically an empty array of never. Meaning you won't be able to put anything into it, or read anything out of it.

I think the type more similar to what jsdoc expresses would be any[].

@englercj You're correct. I've updated the PR.
