contrubition instructions + repo cleanup

[maciejtreder]

Hello,

I would like to contribute to this package (I need an Angular Universal support). Are you going to update your contribution.md file? There is also a lot of cleanup todo here (we could remove all lines not related to ts, create travis job etc. etc.)

Hi @maciejtreder, Sounds good, you're free to change all this. Make a pull request with the changes and I add you as a contributor to github and npm.

Hello,

I'm trying to create a patch, and want to try it locally in my project, After cloning the repo, build and link, (and updating main file path), I still can't use it as I have this error :

ScAppComponent_Host.ngfactory.js? [sm]:1 ERROR Error: StaticInjectorError(ScAppModule)[OrientationInfoRx -> InjectionToken Platform ID]: 
  StaticInjectorError(Platform: core)[OrientationInfoRx -> InjectionToken Platform ID]:

Anybody know how to correctly link and use this package locally ?

Strangely if instead of linking I replace the files in node_modules it just work.

I don't really understand.
