./project make: new texclean target

Until now there was only a 'clean' (to delete all files created during the
'make' phase) and the 'distclean' (to delete all files during configuration
and make). But sometimes we don't want to delete all the files created
during the full 'make' phase, we only want to delete the files that were
created by LaTeX for building the paper.

Witht this commit, a new target has been added for this job. You can now
run the following command for this job:

  ./project make texclean

Only the files in '$(BDIR)/tex/build' will be deleted (and the 'tikz'
directory under that location is recreated, ready for a future build).
