[proposal] Cross-Origin JAX-RS annotations

[Benson Margulies]

I propose to add the following

@CorsAllowAllOrigins
@CorsAllowOrigins(  "origin1.", ... "originN" )
@CorsAllowMethods( "meth1" ... "methn" )
@CorsExposeMethods( ... )
@CorsMaxAge(integer)
@CorsAllowCredentials(boolean)

and make the filter look for them on resources and classes in the usual way.

Any objections?
