in python/spot as well.

for twa_run, and instantiate templates for twa_run's members.

* python/Makefile.am: Use nobase_ for installing python files.  This
required removing the $(srcdir) prefix used almost everywhere in this

an Automake warning.  The downside is that the Makefile probably won't
support VPATH builds with some inferior implementations of Make.
