Add an option to control if StringLiterals in JSXAttributes' value should use double quotes or single ones

[royriojas]

1. Let's call that property JSXAttributeQuotes
2. if the property has a value of empty, null or undefined (in short if falsy) then ignore it, quotes should remain as they were received
3. If the property has a value different from single or double, just ignore it.
4. if the property has a value of single, then make sure all stringLiterals in JSXProperties use single quotes.
5. if the property has a value of double, then make sure all stringLiterals in JSXProperties use double quotes.

Note. Strings should be escaped when needed.

Example:

Given

function render(count) {
  return <input type="text"
 />;
}

and JSXAttributeQuotes is single

then the expected output will be

function render(count) {
  return <input type='text' />;
}

if JSXAttributeQuotes is double and the input is

function render(count) {
  return <input type='text'
 />;
}

then the output should be

function render(count) {
  return <input type="text" />;
}
