Incompatible with node 0.4.x

Love the simplicity of needle, but it looks like needle doesn't really support 0.4.x. Since I'm hosting on heroku, I'm stuck with node 0.4.7.

The main issues are:

• commit 36c797f1 requires a json file. node 0.4.12 can only import js files as modules. JSON import came with node 0.6.x. Not sure how to fix this short of just harcoding the version number and bumping it with each release.
• commit d12105dd depends on the zlib module, which was also added in node 0.6.0. node-zlib exists and conflicts with the new 0.6.x module, but a better option might try/catching zlib and just saying zlib is only supported for 0.6.x.
• commit 8642c3de doesn't quite fix paths for older node, since it drops the query string. As shown in the 0.6.x docs, path = pathname + search

I'll fork and submit a pull request for the latter two, but I'm not sure about the best course of action to fix the first issue.

Hi and thanks for the feedback! Pity to know Heroku is still running Node v.0.4.x.

1. I guess that can be fixed with a JSON.parse(fs.readFileSync('./package.json').toString()).version; Uglier but it works.

2. Good idea. Will do.

3. Thanks for pointing that out, I'll change it pathname + search then.

Final nitpick, might be worthwhile to say:

var request_compressed = (options.compressed && typeof unzip != 'undefined') || false;

to make sure you don't ever request gzip on 0.4.x.

Thanks so much for the responsiveness -- really appreciate it

Ok pushed and published 0.1.7 in npm. Thanks for the feedback again!
