Vanillaplusjs

Improves handling of truly heinous javascript regular expression literals, such as `/[/=]/`

Supports regular expression literals in the javascript tokenizer/serializer, ensuring they are properly preserved.

Fixes deploy scripts

Resolves an issue where strings like `"foo\nbar"` in javascript would be converted to `"foonbar"` instead of preserved.

This release adds support for javascript comments containing just "type-hint" (and optional surrounding whitespace) to cause the line to be commented out.

For example:

js
export function foo(a, b); // type-hint
export function foo(...args) {
// ...
}


will become

js
/*export function foo(a, b); /* type-hint *\/*/
export function foo(...args) {
/* ...*/
}

This adds support for environment variables in constants.js
