Hey,

I'd love to be able to use this library from the client through browserify. There are a few issues currently preventing that from working. First and foremost, browserify cannot detect dynamic require()s, so child libraries aren't loaded.
Eg;

var cls = require("./api/v" + this.version);

needs to be replaced with an if statement, with each branch explicitly requireing its version.

Similarly, in v3.0.0/index.js, the fancy forEach at the bottom has to be replaced with

Util.extend(proto, require("./gists"));
Util.extend(proto, require("./gitdata"));
Util.extend(proto, require("./issues"));
Util.extend(proto, require("./authorization"));
Util.extend(proto, require("./orgs"));
Util.extend(proto, require("./statuses"));
Util.extend(proto, require("./pullRequests"));
Util.extend(proto, require("./repos"));
Util.extend(proto, require("./user"));
Util.extend(proto, require("./events"));
Util.extend(proto, require("./releases"));
Util.extend(proto, require("./search"));
Util.extend(proto, require("./markdown"));
Util.extend(proto, require("./gitignore"));
Util.extend(proto, require("./misc"));

Uglier code, perhaps, but it would work on Browserify. Well, that's the first step - use of fs to read JSON would need to be replaced with requireing instead. I didn't make it past that =)

Would be understandable to not support this as well, of course. But would be pretty cool to have.

Cheers!
