Query update with current package

[geof90]

Edited the code to

• Save current package info to a file on installing a new bundle from the server
• Get current package info from disk and send to server for comparison when querying for updates

put spacing between if and opening paranthesis, similarly for else and braces.. that is our coding guidelines.
feedback throughout the code.

If someone has a link to the coding guideline page, that would be great for Geoffery.

Reduce redundancy by combining logic;

var defaultPackage = {appVersion: configuration.appVersion};
if (!err && localPackage !== null && localPackage.appVersion === configuration.appVersion) {
defaultPackage = localPackage;
} else if (err) {
console.log(err);
}

sdk.queryUpdateWithCurrentPackage(defaultPackage, callback);

done

I should have mentioned this before, final change:

if (!err && localPackage && localPackage...)

checking this way verifies localPackage against null and undefined.. dont need an explicit null check.

LGTM!

You should wait on @itsananderson to signoff for the objective C changes..
Obj C looks good to me, but Will would be in a better state to identify issues with it.

Sorry for the delayed review. LGTM once you remove the temp file.
