stats.lua: scroll: allow throttling page-rebuild (no-op)

Browse Source 
Typically the current page is rebuilt and rendered once per second,
howeve, scrolling can invoke the rebuild function very frequently,
even at a rate which is too fast for the rebuild function to keep
up. This can result in high CPU usage and input lag.

This commit adds an argument to the page-rebuild function, letting it
know whether or not it's called following a scroll keypress, thus
allowing it to cache intermediate data so that it doesn't have to
re-calculate the whole page from scratch.

This additional argument is unused currently, but it could be useful
for the internal performance page - which can be relatively heavy.
