fix Pair tag getStyle() execution failure ，see issus #77

The changes to the Style resolver seems fine to me and all changes associated to this: KmlStyleMap, Pair, StyleResolver.
What I don't understand is why the change in the jszip.js What is the reason behind this change. The rest seems ok for the merge, but I need to understand this one. Could you provide some example of file, which works incorrectly without this change?

In KmlFile.js ，
The 83 line.

83 kmzFile.files.forEach(function (file) {
84 if (file.endsWith(".kml") && rootDocument == null) {
85 if (file.name.endsWith(".kml") && rootDocument == null) {
86 rootDocument = file.asText();
87 }
88 });

The kmlFile.files is a object ,not a array , can‘t use forEach method .
So i change the jszip.js ， let it return a Array .
Maybe I'm not doing it right. Just to solve the problem, without considering the rationality.
Sorry for this .

I missed this one. Don't change the jszip. Instead this code should be changed. It should be working if it is changed to:

Object.keys(kmzFile.files).forEach(function(key){
    var file = kmzFile.files[key];
});

Retrieve all the relevant files and then manage the previous function on each of them. Is it obvious what I am trying to explain?

Maybe you can help me with this #84 ，

[QingMings]

yes, I understand，I will correct it。:)
