Display error message for invalid zip errors

[marcelgerber]

If an error occurs in decompressZip, the returned error will be displayed to the user.
This hopefully helps tracking down adobe/brackets#7387.

Diff of package-validator.js:

 function extractAndValidateFiles(zipPath, extractDir, options, callback) {
     var unzipper = new DecompressZip(zipPath);
     unzipper.on("error", function (err) {
         // General error to report for problems reading the file
         callback(null, {
-            errors: [[Errors.INVALID_ZIP_FILE, zipPath]]
+            errors: [[Errors.INVALID_ZIP_FILE, zipPath, err]]
         });
         return;
     });

@marcelgerber You need to update package-validator.js in Brackets, and then update brackets-extensibility.tgx from Brackets.

@marcelgerber Does the .tgz change here still match the package-validator change that landed in adobe/brackets#10343? If so then @redmunds is this ok to merge now?

[marcelgerber]

It doesn't include the updated version number in package.json.
I too think we should wait for Ingo's dependency upgrade PR to be merged first.

I assume we are waiting for adobe/brackets#10372 to land
