Moved the load event emitted from DocBaseViewer from pagesinit to the first pagerendered event for PDFJS.

Also modified the emitLoadMetrics() method in Preview.js to include a meaningful_content_timestamp which can be used to calculate Time to Meaningful Content (TTMC)

Should this be contentLoadTimestamp to stay consistent with its other attribute? Should it default to 0, as well?
