Fix for finding file identifier in add-launch-to-msi.js

[mcantrell]

jpackage created an MSI with a LongFileName|ShortFileName format which caused the lookup to fail. I ended up using the FindFileIdentifier function in this post to resolve the identifier:

You may want to consider enhancing your script to account for these differences if you stumble upon the same issue.

This is great, probably explains an error someone else ran into. I'll merge it in after the holidays, or if you want to send in a PR that would be great.

Replacing this part:

sql = "SELECT File from File where FileName='${app.name}.exe'";
view = database.OpenView(sql);
view.Execute();
var file = view.Fetch().StringData(1)
WScript.StdErr.WriteLine(file);
view.Close();

with

var file = FindFileIdentifier(database, "${app.name}.exe");

worked.

Thanks.

BTW what is the command line equivalent of the goal in the exec-maven-plugin for this? It must be something like:

cd target
cscript packaging/add-launch-to-msi.js [SOME OPTIONS  HERE]

I don't want to run mvn:install for every try.
