.jar binding doesn't like binding constant fields that have embedded newlines.

To reproduce, bind json-org.jar from:


Or see the conveniently attached project. ;-)

The problem is that there are two fixups that are required in order to bind json-org.jar; from Transforms\Metadata.xml:

>  <remove-node path="/api/package[@name='org.json']/class[@name='HTTP']/field[@name='CRLF']" />
>  <remove-node path="/api/package[@name='org.json']/class[@name='Test.1Obj']" />

We can't bind the HTTP.CRLF field, because it has an embedded newline in it. This causes `generator` to produce:

    public const string Crlf = "

which makes the C# compiler angry. We should instead generate:

    public const string Crlf = "\u000d\u000a";

(We should probably unicode-encode any character outside the range 0x20 through 0x7f as well, though this might also break surrogate pairs...or can \uXXXX\uYYYY be used to do surrogate pairs properly?)

The second problem is the org.json.Test.1Obj class, which can't be bound because it starts with a number. Firstly, it shouldn't be bound (it's not public!). Secondly, any type that starts with a number should just be skipped, not bound.

String literal part is fixed.

Numeric class issue also fixed.
