Spec compliant media type parsing

Parsing media types is actually very complex, and previously Play was
doing a hacky series of splits, which usually work, but as soon as
something slightly different from what typical clients send came, would
not work at all.

The following changes have been made:

* New MediaType class that has the type, plus a sequence of the
  parameters, parsed according to RFC 2616, so they support everything
  including quoted parameter values, parameterless values, etc etc.
* New mediaType method on RequestHeader for parsing the Content-Type.
* contentType and charset methods on RequestHeader now use the new
  mediaType method to correctly parse the header.
* multipart/form-data now uses the mediaType method to correctly get the
  boundary parameter, fixing #1399.
* MediaRange now extends MediaType, and has a q value and a sequence of
  accept extensions.
* MediaRange sorting is now stable, equal q value/specificity media
  ranges are in the same order as in the Accept header.
* Matching of types, sub types and parameter names is now down case
  insensitively, in accordance with the spec.  Previously contentType
  was always converted to lower case (in a way that was susceptible to
  the turkish i bug), now it's left alone.

The new parser uses Scala parser combinators.  In order to correctly
parse quoted parameters, a parser like this was necessary, since
delimiters may appear in the quoted values, which would break split. A
benchmark of a relatively complex accept header (6 elements) showed it
takes 40us to parse it on my machine.

At some point in future we may decide to extract some of the parsing out
into a generic class for reuse in other parts of Play, but for now I
just wanted to get this fix finished without over engineering.
