Makefile for python bindings to speech tools

[ddavout]

the repertory
speech_tools/wrappers/python seems missing in this version

[lenzo-ka]

There is a lot of work to be done here. It's not too hard to get the swig wrappers up with modern swig and so on, but there are still issues such as a total crap out when EST tries to allocate big memory under python. The prior python bindings are far out of date and were removed for being more trouble than benefit at the time. It is going to take a concerted and more modern effort to make these bindings viable -- which I think is quite important, but we need someone to take it on.
