Handle local files better in server mode

Handle local files better in server mode

We're already serving sources from the original directory (for source
maps).  This lets us serve other resources as well.  Makes it simpler
to run angular todo and other apps with xhr'ed data.

server mode ಠ_ಠ  ;)

Code change LGTM tho, w/ a suggestion (I think there should be a way to do this
using shelf's built in capabilities. Up to you though).

https://codereview.chromium.org/1644673002/diff/1/lib/src/server/server.dart
File lib/src/server/server.dart (right):

https://codereview.chromium.org/1644673002/diff/1/lib/src/server/server.dart#...
lib/src/server/server.dart:265: if (response.statusCode == 404) {
this feels a little bit off wrong in the architecture. Shouldn't we be able to
chain request handlers without manually checking for 404?

My understanding of Shelf is that it should support multiple kinds of handlers:
https://pub.dartlang.org/packages/shelf

Anyway, not a big deal...
