Fix for zone.js error in Safari, Added Typings

[marvinscharle]

This PR contains the following changes:

• Updated tsconfig.json to maintain tsconfig schema
• Updated package.json to include all required packages (there are currently some missing)
• Fixes zone.js error (More tasks executed then were scheduled) in Safari by removing NgZone from FileItem: Since zone.js 0.6.12, callbacks / observables are evaluated correctly in angular's zone by default. Therefore calling NgZone#run is not necessary anymore.
• Updated both FileUploader and FileItem to include correct type specifications to check against in controllers that include ng2-file-upload

Looks really good, please apply comment and rebase on top of dev branch

PS are you using npm 2?

[marvinscharle]

Applied as suggested.

@valorkin yes - currently we're working with npm 2. Therefore some of those "missing" packages are non-flat dependency related.

[valorkin]

Looks really good now! :)

PS: no need to fix, but:

• ng2 is all about npm 3, or you will face a lot of weird issues
• set save-exact for npm :) (non strict deps is a pain :))

Thanks for merging @valorkin

npm 3 is much better, indeed. But ionic2 currently sings better with node 4.x. Therefore, we are using its built-in package manager - and that's unfortunately npm 2.

Is this fix already available? Because in my safari browser on my mac, the single file upload on this page is not working: http://valor-software.com/ng2-file-upload/

[marvinscharle]

It should been fixed. Can you post the error message you're receiving?

In Chrome it works ok.

In safari on my mac, the progressbar is already 100% before I have clicked the upload button.
And after uploading, the status is not updated and stays empty.

This is the error I see in the console:

@Can't find variable: Intl - Until now Safari does not support native i18n. This means that this is not related to this PR.

This polyfill should solve this issue: https://github.com/andyearnshaw/Intl.js/

Can you please open an issue for this @lderks?
