HttpServerRequest headers names are not case insensitive

[ddossot]

org.vertx.scala.core.http.HttpServerRequest uses Scala's collection.mutable.MultiMap which is not case insensitive, preventing headers to be correctly retrieved when the case in their names don't match.

In other vert.x langs, this works as expected, ie header names are case-insensitive.

This will change with #51 to use org.vertx.java.core.MultiMap internally. It would be great if you could check out the branch I'm working on (Narigo/complete-api), to see if it's still an issue there. And I'd be happy to have a pull request with a test for this :)

Thanks!

This has been fixed in #136 and we make sure header names are lower cased internally.
