1.0.9+1

Closed #162, fixing a caching bug that would cause multiple requests to the same URL to fail.
Resolved dependency injection of primitives (namely String), no longer triggering errors about String has no constructor, etc.

1.0.9

Closed #161. addCreated/addUpdatedAt no longer crash when serialize is false.
Added an explicit on charcode, path, and others. Resolves #160.
ResponseContext now implements StreamSink<List<int>, so data can be streamed directly to the underlying response.
You can now inject encoders into a ResponseContext, which takes care of Accept-Encoding. This will ultimately replace package:angel_compress. Resolves #159.

Changed req.query to use a modifiable Map if the body has not parsed. Resolves #157.
Changed all constants to camelCase, and deprecated their CONSTANT_CASE counterparts. Resolves #155.
Resolved #156 by adding a graphql provider.
Added an analysis-options.yaml enabling strong mode. Preparing for Dart 2.0.
Added a dependency on package:meta, resolving #154, and added corresponding annotations to make extending Angel easier.
Resolved #158 by using proper StreamController patterns, to prevent memory leaks.
Route handler sequences are now cached in a Map, so repeat requests will be resolved faster.
A message is no longer printed in production mode.
Removed the inheritance on Extensible in many classes, and removed it from angel_route. Now, only Angel and RequestContext have @proxy annotations.
Deprecated passing debug to Angel.
_LockableBytesBuilder now uses Uint8List.
Removed reopen from ResponseContext.

Changed ResponseContext.serialize. The contentType is now set before serialization.

Moved the Model class into package:angel_model. No functionality was added or removed.

Added an accepts method to RequestContext. It's now a lot easier to tell which content types the user accepts via the Accept header.
