Going public AccessorProvider

Annotating modelPropertiesProvider with @Qualifier
 #367 Fixes issue with application context having multiple RequestMappingHandlerAdapters

 #367 Uses equals to compare class name

Reproduces issue #367

Fails test when adapter is an autowire candidate
Improvements of #353

@ApiImplicitParams & @ApiImplicitParam are now read on class interfaces

Include OSGi headers in the manifest so that the JARs can be used
in a OSGi container such as Eclipse Virgo.

The new headers should not impact non-OSGi usage in any way.
