[pycon-za] Confirming first few speakers

[Simon Cross]

Greetings

We have firm offers for talks from:

* Larry Hastings (Stepping through CPython -- his PyCon US 2012 talk)
* Armin Rigo & Maciej Fijałkowski (New Approaches to Concurrency in
Python -- a talk about STM, the GIL, etc)

And from:

* Edward van Kuik (How to open a bar in Python)

Edward is a long-time CTPUG supporter, owner of nitric.co.za and
currently runs a bar with a lot of funky features using software he
wrote himself in Python.

If there are no objections (speak now) I'd like to accept these three
talks just to get the speaker ball rolling.
