Title: Adding the skeleton work for the wtf-json file format.

This lets you open both wtf-trace and wtf-json files in the UI. If the
files are loaded together (dragged in/ctrl-o/etc) then they will be
loaded into the same database correctly. The loader isn't currently
implemented, pending some TraceSource cleanup.
