__non_webpack_require__ -> require in SystemJS

When running browser tests, e.g. via `gulp unittest`, the test files are not
processed by babel, and neither by the "unittestcli" gulp target.

This commit copies the babelPluginReplaceNonWebPackRequire plugin from the
unittestcli target to the SystemJS config so that `__non_webpack_require__` is
replaced with `require` for all build targets, and adds a unit test to ensure
that this indeed works as expected.

Fix display_svg_spec tests.

- Mark the test as async, and don't swallow exceptions.
- Fix the DOMElement polyfill to behave closer to the actual getAttributeNS
  method, which excludes the namespace prefix.

Optimize PNG compression in SVG backend on Node.js

Use the environment's zlib implementation if available to get
reasonably-sized SVG files when an XObject image is converted to PNG.
The generated PNG is not optimal because we do not use a PNG predictor.
Futher, when our SVG backend is run in a browser, the generated PNG
images will still be unnecessarily large (though the use of blob:-URLs
when available should reduce the impact on memory usage). If we want to
optimize PNG images in browsers too, we can either try to use a DEFLATE
library such as pako, or re-use our XObject image painting logic in
src/display/canvas.js. This potential improvement is not implemented by
this commit

Tested with:

- Node.js 8.1.3 (uses zlib)
- Node.js 0.11.12 (uses zlib)
- Node.js 0.10.48 (falls back to inferior existing implementation).
- Chrome 59.0.3071.86
- Firefox 54.0

Tests:

Unit test on Node.js:

```
$ gulp lib
$ JASMINE_CONFIG_PATH=test/unit/clitests.json node ./node_modules/.bin/jasmine --filter=SVG
```

Unit test in browser: Run `gulp server` and open
http://localhost:8888/test/unit/unit_test.html?spec=SVGGraphics

To verify that the patch works as desired,

```
$ node examples/node/pdf2svg.js test/pdfs/xobject-image.pdf
$ du -b svgdump/xobject-image-1.svg
 # ^ Calculates the file size. Confirm that the size is small
 #   (784 instead of 80664 bytes).
```
