Add quick-repeat-list interpolation

[llchan]

This adds simple interpolation of the quick-repeat-list variable. There may be a better way to do this but this worked for my case. It is important to note that the variable is not watched like a typical interpolated attribute. We may want to add that option in the future.

I'll check it in the next couple of days

@llchan can you also add these changes to the quick-ng-script in example directory?

Hey @llchan what about my suggestion? I want to merge this as soon as possible

[llchan]

Should I just update the example to be functionally the same but have an interpolated list name internally? In practice you probably wouldnt use it unless you have at least 2 lists to render but I dont know if we want to change up the example so much.

@llchan actually we don't. Let's just make it the same file

If I manually merge this should this support a nested ng-repeat too ?

Because the below snippet doesn't work for me (with or without manually merging this PR)

<div ng-repeat="item in mylist">
    <div quick-ng-repeat="child in list" quick-repeat-list="item.children">{{ child.title }}</div>
</div>
