Inlude the JS actions for the page when dispatching the "pageopen"-event in the BaseViewer

Browse source 
Note first of all how the `PDFDocumentProxy.getJSActions` method in the API caches the result, which makes repeated lookups cheap enough to not really be an issue.
Secondly, with the previous patch, we're now only dispatching "pageopen"/"pageclose"-events when there's actually a sandbox that listens for them.

All-in-all, with these changes we can thus simplify the default-viewer "pageopen"-event handler a fair bit.
