Add typescript types

[ilari-makimattila]

Add definition files for Typescript. Fixes #117.

HTTP request and response are typed to corresponding axios objects. Mainly because I don't have motivation to test other providers.

Suggestion - in index.d.ts, add a constructor to the VueAuthenticate class declaration so it can be instantiated with new, as per the Vuex example in the README.

eg:

import {AxiosResponse, AxiosRequestConfig, AxiosInstance} from 'axios';

export declare class VueAuthenticate {
  public constructor($http: AxiosInstance, overrideOptions: AuthenticateOptions);
  
  // .. other method declarations 
}

Also, withCredentials seems to be a valid flag for AuthenticateOptions and should be added.

export interface AuthenticateOptions {
  withCredentials?: boolean;
}

Thanks. I added the missing definitions. In the meantime I stopped using this library because it's missing some features I needed and it turned out to be more effective to just write one myself. I'm happy to support with merging this though.

Hi @ilari-makimattila , thanks for this PR. Can you please tell me which features are the key ones and the reason why you stopped using VueAuthenticate?

One thing bothers me here. You made typings for Axios only ($http: AxiosInstance), but this library can use any request library (previously, Vue-resource was default library). What happens when you pass Vue-resource library to handle network requests?

I see that you don't have motivation to test other libraries, but i can't merge half-finished work into master.

We decided to go with a hosted solution instead of managing our own user database and it felt easiest to just write a vue plugin instead of looking for an existing solution.

These types would more or less force any typescript user to use axios. But to be honest I don't really know how to write the type declarations in a way that wouldn't force the you to do explicit casts for every return value.

Hi, what is the status of this? I see there has been no activity in a while and the contributor who started it has stopped using this library. Is is worth picking up or are there no plans to integrate types?

Cheers
