feat: include type defintion

[PatrickJS]

I need this for Universal Angular 2 which uses typescript

update: could you also release a patch update

I'm not definitely saying no to this patch, but is there another way of accomplishing its goal? Does TypeScript really expect to creep into every package in your system?

[PatrickJS]

yeah, there is a typings manager but the most seamless way is having the repo itself provide the types so there won't be any version conflicts. soon we won't need "typescript": { "definition": "xhr2.d.ts" }, when tsd (legacy types manager)

[pwnall]

This repo's goal is to implement the W3C XHR2 spec. Given the state of the spec, it is unlikely that the public API provided by the repo will ever change. Based on the xhr2.d.ts contents I've seen in the PR, it seems like there would never be an opportunity for a versioning conflict. Am I understanding this the wrong way?

[pwnall]

Just to be clear about my intentions: I don't want to make your life hard on purpose. I'm pushing back because I'm not too thrilled about potentially having to include dedicated code for every language that compiles to JS out there.

If the alternative has a terrible price (e.g., if every Angular user has to create that .d.ts file) then I will look into what it'd take to get some test coverage for this definition and merge it.

[PatrickJS]

every angular (ember is also going to use typescript) users would have to do a typings install xhr or create their own defintion. If someone installs their XMLHttpRequest then it will merge with this definition which includes the non-standard nodejsSet that I requested before. I can also volenteer to keep the definition file updated
