Parser syntax errors should be passed to the callback, not thrown #12

When the parser encounters a syntax error, it currently throws a SyntaxError exception instead of bubbling it up to the render callback like I'd expect. Catching this exception is proving to be a challenge in an Express app. I'd much rather be able to handle it in my callback.

Can you gist this or post the code here?

This will throw a SyntaxError in Node (run it as a file, though; the REPL catches and hides the exception):

var dust    = require('dust'),
    context = dust.makeBase();

dust.renderSource('{<body}no end tag', context, function (err, html) {
    if (err) {
        console.log('I got an error!'); // never gets here

This should be an easy fix. I'll push it out in the next version.
