feat(lint): parse inline templates

[mgechev]

This PR contains slightly more stuff that it is supposed to so I'll be more explicit with the explanation of the changes:

• - Template support. We now parse inline templates with the Angular TemplateParser and perform linting over them. There are a couple of limitations:
  • We support only inline templates. Plugging support for external templates is a topic for another discussion but the current PR introduces pretty solid base for this.
  • We don't provide very precise position of where the error has occurred. At this point because of not very detailed information in the sourceSpan in the nodes produced by the TemplateParser we cannot get very accurate information about where the actual linting error is. This issue is tracked by fix(template): mark the entire expression as invalid when the linter finds an error #88.
• - Linting for src/**/*.ts and test/**/*.ts. Since the project gained some popularity recently (7-8k downloads per day on npm), it'll be good to enforce some common coding style. In other words, I took the tslint.json from angular2-seed and placed it here. This task will be also run in CI (currently the CI fails because the task will be introduced by this branch).
• - Aligns to the style rules introduced by tslint.json.

During the testing, I found problems with parsing
templates when pipes are not declared in same scope.
The other issue that I found was problem parsing "object.property" expressions .
