Timestream data inspection

[pszjmb1]

Currently an artist can only view 500 datapoints at a time in a timestream and then needs to click prev/next. It should be made easier to inspect the data. Some ideas:

• Add pagination details such as number of points shown, number of pages, links to pages and first (there's already a button for latest).
• Add links to statistically relevant data such as largest and smallest values
• Have some kind of data aggregation to allow for an overview of the data (a fully zoomed out perspective)
• date search
• context search
• button to display the data around where the playhead is
