Also update dart_to_js_script_rewriter dependency to ^1.0.1, and change most angular2.dart imports to be core.dart instead. The pipes example broke without the angular2.dart import, so I let it be. The server-communication sample has never worked for me, so I changed it but might have broken it further. closes #1007
