Clean up systrace a bit.
Extract the various event definitions into a table instead of a
switch statement.
Add a --link-assets option to systrace.py to generate a trace.html
file that has the CSS and JS assets linked in rather than embedded,
which is useful for debugging purposes.
Fixed a bug in the tests for lineRE.
