Pre-build nodeunit for browser

[brettz9]

Hi,

I'm on Windows and at least for the Make tool utility I am using, I'm not able to get it work.

Can you please pre-build the browser file or else supply some kind of platform-agnostic build tool (like grunt perhaps)?

I see I can workaround this by using the file in the examples/ folder, but I figure that might not be as stable...

@brettz9 the makefile is here:

https://github.com/caolan/nodeunit/blob/master/Makefile

the commands used in there may be available in cygwin or some other shell. PR welcome!
