Bug #37 - Instrumenting e4x causes: jscoverage:filename:983: unsupported node type (73)

I'm attempting to instrument a project that makes extensive use of e4x. Every
file that contains an e4x statement like:

let etag = multistatus..D::getetag;

or even:

let linkifiedText = <p/>;

Cause one of the error messages:

jscoverage:filename:983: unsupported node type (73)
jscoverage:filename:62: unsupported node type (75)

Yes, unfortunately JSCoverage cannot handle anything beyond ECMA-262 3rd edition.

Here's a partial patch, not made to be complete and probably nowhere near good
style, but it "just works" for my use case. Maybe someone can make more out of this.
