refactor: change method used to report statistics.

The old way used a hard coded list of timing statistics. It could be
translated, but required revising every time a new stat was added.
The elapsed time is always calculated, so keep that as a translatable
item.

Now dump all other stats in the timing dict. I can add new timing
values and get them dumped without addition changes.

Also check the type of the result. Only process timing if it's
text/html. I can't report it otherwise. Also templates like
_generic.translation can override the result type. Before it was
generating stats for every request even if it couldn't display
it. Also if '</body>' showed up in a js file or a comment in an image
file doing the substitution would break the data.
