Add codelyzer

[SamVerschueren]

codelyzer could enforce the Angular2 styleguide. Might be a nice addition to add that.

See ng-be/app-ng-be-org#4 (comment) for the context.

@SamVerschueren I've been doing this in the branch "codelyzer" but I have some issue with node_modules being linted, can you take a look please? :)

[SamVerschueren]

@samvloeberghs Do you get the error in compiler.umd.js? It's a very strange error I get.

template.animations.forEach(function (entry) { triggerLookup.add(entry.name); });

I dived into the task where the linting code is being fired, and basically it invokes the linter like this

$ tslint --config tslint.json src/**/*ts

Which is correct and shouldn't include node_modules. So the compiler.umd.js error comes from somewhere else.

I took a look at Google and came here. Issue that tracks this in codelyzer can be found here.

I will submit a PR against the codelyzer branch that removes the rules that can't be used right now.
