Ports committer needed for 4 new py-* ports

[Vladimir Chukharev]

Hi,

The ports of the set are connected. The main port is py-mayavi, and the others are needed by it.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204435 204435 [NEW PORT] graphics/py-mayavi: Application and library for 3D visualization and plotting in Python
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204433 204433 [NEW PORT] graphics/py-traitsui: Toolkit-independent GUI abstraction layer for the Traits package
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204432 204432 [NEW PORT] devel/py-pyface: Traits-capable windowing framework from Enthought
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204431 204431 [NEW PORT] devel/py-apptools: Enthought application tools
(Fifth port of the set, devel/py-envisage, has been committed long time ago and later updated.)

All the ports were discussed in Phabricator ( https://reviews.freebsd.org/D4181 ).
The raised issues resolved, no more comments followed after that for a long time.

I use both the application and library successfully on my computer for half a year (python27).
The application can be started like this:
LD_LIBRARY_PATH=/usr/local/lib/gcc48 mayavi2

(The need for an environment variable belongs to other ports. At least, math/py-numpy needed this. And probably some other dependences too...)
