[Gridflow-dev] [patch] fix bug in adding Pd paths when paths were empty

[Claude Heiland-Allen]

$ cd ~/src/gridflow && pd -lib gridflow
opening examples/doodle.pd can't create [#mouse]
$ cd ~ && pd -path src/gridflow -lib gridflow
opening examples/doodle.pd can create [#mouse]
$ cd ~/src/gridflow && pd -path nonsense -lib gridflow
opening examples/doodle.pd can create [#mouse]

I made some changes to fix the case of no -path, see below.  With this fix:

$ cd ~/src/gridflow && pd -lib gridflow
opening examples/doodle.pd can create [#mouse]

Thanks,

Claude
