adding optional require.js support

how to enable require.js support:
- create a subfolder called `rjs`(can be overwritten via `requireSubFolder` setting) in app/assets/javascripts/
- add require.js managed js files to this folder
- add  `<script type="text/javascript" data-main="public/javascripts/rjs/main" src="@controllers.routes.Assets.at("javascripts/require.js")"></script>` to your template where data-main is the js file name in question

things to know:
- require.js is bundled with play, so users do not need to add it manually
- in dev mode dependencies resolved client side, closure compiler, without commonJS support, is run through the scripts for sanity check but no files are modified
- in prod mode: stage, dist and start commands were changed to
run require.js' optimizer for each file in app/assets/javascripts/rjs this means files will be minified and combined for performance. Since the files (and references) will be the same (just optimized), no extra changes are necessary to switch between dev and prod mode
- by default a rhino based optimizer is used, the native, node version can be configured for performance via `requireNativePath` setting
- if app/assets/javascripts/rjs is missing, no extra processing takes place, so the default behavior will be used
- right now this is enabled only for javascript but we are looking into using it for css as well

upgrading play to sbt 0.12.0

As the first step in our quest to move to scala 2.10, play is now upgraded  to sbt 0.12.0.

Things to know:
- play is on scala 2.9.2 now
- sbt plugins were updated to 0.12.0 (sbt-idea will be updated to 1.1 final in a separate changeset)
- tests are executed in fork by default (so no more permgen issues!)
- forking has some minor overhead but not much
- forking required adding some extra clean up tasks to test helpers (both java and scala) in order to avoid test hanging
- Promise's actor system and WS' threads now can be cleaned up properly during test execution
- forking can be turned off via the standard `fork in Test:=false` setting
- if you experience hanging while running tests, make sure all your threads are shut down
- resident compiler is still turned off due to issues with empty packages,
this feature will be enabled once we are on scala 2.10 M6 (with the fix for SI-5939)
Add a Date header to 304 responses

This change adds a Date header to 304 responses and fixes an issue with CloudFront getting stuck in a RefreshHit cycle after hitting the TTL.

More information about why the Date header is required on 304 responses can be found at:
http://stackoverflow.com/questions/1587667/should-http-304-not-modified-responses-contain-cache-control-headers

Also, since a Date header should always be returned (not just for requests that have a Last-Modified header) the Date header is now set when a 200 response is constructed.

The FunctionalSpec has been added to test for the Date header on a 304 response.
fix Promise.system's visibility that was incorrectly changed to public during 0.12.0 upgrade
fix console reader issue after sbt 0.12 update
upgrade sbt-idea to 1.1.0 final
some apis + core refactor for introducing the filter method
disable fork in Test for the time being
refactorings for introducing onRequestCompletion in Global file
fix last commit for unkown length body
now tests pass
now onRequestCompletion is called on response sent or socket closing
[#413] make sure require.js works with js modules in subfolders
fixes #665: enumerate all the jars in the same order as sbt, instead of using lib/* which makes the order of the classpath random. see ticket for more info
ignore idea, eclipse, and pid files
