[FEATURE] Added sort order for each column and faster filtering without re-paint

* Each package is now using an `ObjectProxy` with aliases and useful properties
* The search filter is debounced very 100ms
* The search is simply hiding `tr` by css classes which is much faster and does not need re-generating each row
* You can now order by clicking on each column, default sort order being the package name
i would then actually just make `this.store.find('addons')` do this under the hood.
