Update raw-api-definitions

If you type nil followed by an carriage return, Corona Editor will try to replace nil with "network.setStatusListener( hostURL, listener )" thinking you are trying to do a substitution.

So trying to nil out variables ends up being a frustrating game of removing network.setStatusListener( hostURL, listener ) from each line.

By putting nil in the completions, it should leave it alone and it is a reserved keyword anyway so it would be nice to have it there.
