Start converting specs to jasmine
Run all tests. Bump to vertx 2.1M4-SNAPSHOT
Bump jasmine-jvm version
Remove NodeJSGlobalObject factory and initialize things in node.js.

As much as possible, try and eliminate any Java runtime initialization
and intstead, do it all in JS. For now, that means initializing the
Buffer and QueryString types in node.js. Any non-vertx client can now
use nodyn by simply supplying a __jvertx object in the global scope, and
then load()'ing npm_modules.js and node.js. See
src/test/javascript/specHelper.js as an example.
More jasmine file system tests.

Also:
 - Bump version dependency of lang-dynjs.
 - Just put npm_modules.js directly into our source.
