-The manifests for framework and flex4 will now be maintained from the frameworks/halo-manifest.xml and frameworks/spark-manifest.xml instead of maintaining duplicate copies.
-added back the flash.filters classes
-added lookupOnly="true" for classes that refer to other swcs
-mxml-manifest.xml is removed from SVN but is now copied (during the build) from halo-manifest.xml and will still remain in the frameworks directory just not under src.
-renamed the airframework manifest files to be more air specific
-removed bundles.properties as they should not be checked in because they are created during the build.xml
-update flex/flex4/.project to have the spark-manifest link to point at frameworks/spark-manifest.xml
qa: yes. there may be an issue using the flash.filters when using multiple namespaces
tests: checkintests pass
