New activity: Speak

[Joshua Minor]

Hi everyone,
   I made a new activity called Speak.  It is a talking face for the  
XO laptop. Anything you type will be spoken aloud using the XO's  
speech synthesizer, espeak. You can adjust the accent, rate and pitch  
of the voice as well as the shape of the eyes and mouth. This is a  
great way to experiment with the speech synthesizer, learn to type or  
just have fun making a funny face for your XO.

I hope you like it.

Thanks to Arjun Sarwal, Hemant Goyal and Bernardo Innocenti for their  
advice while making this.

Also, if anyone has experience or ideas on how to get access to  
espeak's per-phoneme timing data from python, please let me know.
