Default mode for parameterized plots

[stoch]

With the introduction of cluster queries, many plot view have become parameterized. This complicates the display of plots which use D3 graphics.

After giving the parameter and pushing > to execute the query, it should still show the plot (if saved as such).

It is also desirable to run the query in whatever mode was used before saving the view (tail mode, passthrough, goto end, scan to end). This is valid also for parameter-less views which are called using 'Browse Data'.
