Add note about scala version upgrade
Merge pull request #1427 from benmccann/scala-ver-doc

Thanks so much for this @benmccann
Map key and values are encoded directly instead of having the entire key value concatenation encoded. This permits special characters to be used in key and value values.

Test coverage has been provided.

In addition the delimiters used for encoding have been changed to '=' and '&' given that these are permissible characters to appear as cookie values according to RFC 6265: http://www.rfc-editor.org/rfc/rfc6265.txt

Cookie encoding issues
redirect methods should return SimpleResult so that cast is not necessary to use in Actions

redirect methods should return SimpleResult so that cast is not necessary to use in Actions
More tests on cookie encoding/decoding to reduce paranoia

Make the play run classloader and classpath configurable
Adding hooks for play run lifecycle, so we can track things
inside activator, or other play-plugin additions.

* Deprecate old PlayOn* settings
* Create a new PlayRunHooks trait to listen to lifecycle events
* Add PlayRunHooksTask, that is retreived when play-run is called
Abstract out the 'user interaction' in the run task.

* Fix bug with JLine2 upgrade where Ctrl-D isn't recognized
* Add PlayInteraction trait that describes how play blocks for input.
* Wire in the default interaction mode as Console/Terminal.
Make the play reloader classloader configurable

Create the reloadable classloader with a classloader creator function.
Partition the full runtime classpath into dependencies and user classes.
The run task should be scoped to "Compile" config to match sbt.

Otherwise, we still have shadowed run tasks and oddness.
Run hooks have to be pulled from state, or they are remembered by the Parser.
Add some more exception handling so we don't crash randomnly.
