Embed files

[LorenzGardner]

Add support for embedded files.

provided an array or resource files to embed nexe will now base64 encode the files into strings in a new module nexeres. From inside your application doing a require('nexeres').keys() will give you back an array of all the embedded files. and require('nexeres').get(fileName) will give you back the given file.

They fileName is a string match, and to the relative path from the resource root dir. The hello world example has been changed to embed the message.txt file as an example.

I tested this with a web server that added 125 static files as embedded files. Performance was good, but then again total memory foot print was less than 3mb. I would expect things to go bad if you tried to embed say a large video file.

If you still want to run your app as normal node app you will need to wrap a require('nexeres') in a try catch statement and when not present use fs.readFileSync to get the data.

Love the idea of using res in this, I'll check this out later and make sure it doesn't create any issues. However from how it looks, a breif skim, it should be fine. Thanks for the work!

Works great!
