ttools: inform stilts of new plot2 tasks

Add entries to the Stilts task factory for the new plot2 tasks.
Note these may change name or sequence in the task list at some
point in the future.

Additionally make some logging tweaks to some of the build machinery,
since with the inclusion of these new task the build process invokes
some code which makes unwanted INFO-level reports through the logging
system at build and test time.
