Add Hasler tape viewer for the simulator's physics logs

Reads physicslog/*.dat and draws each trip as a Hasler tape or, for vehicles
with an electronic recorder, as an evaluation screen. Tapes are grouped by
launch, and a launch still running can be followed live. Includes whole-tape
PNG export and a summary of times and averages. With the log off, the page
offers to turn it on.
