Log Message:
Update py-notify to 0.2.1. Resolves PR pkg/47698.

From http://download.gna.org/py-notify/:

"Releases in 0.1 development branch are still available on a separate page
for historical purposes. There is no reason to use them in production:
current stable 0.2 is both bug-free and faster, and more features can be
found in 0.3 development releases."

Package no longer needs buildlink3.mk file, as there is no shared library
installed. PLIST has many entries in PYSITELIB. Package uses PYDISTUTILS
to handle everything. pkg-config, libtool, and gmake are no longer needed.
HOMEPAGE and MASTER_SITES were updated. Added LICENSE. Passes pkglint.
