== Detailed Description ==
The feature add a service to provide text to speech, and a device in the frame to configure pitch and velocity.
A already reserved alt-shift-s key stroke say the selected text in any activity.
The actual implementation does not add any new dependency, and a initial version has been sent to sugar-devel for review.

Text to speech is a good feature to kids, when they are learning to read, and to kids with disabilities.
This feature does not cover the more complex uses of text to speech, like multiple languages and word highlighting.
In the future, we can move part of this code to sugar-toolkit to do easier to the activities use TTS and avoid duplicating code.
The backend can be changed in the future too, if you see there are better voices for example in Festival. Doing the change in a single place will be easier than modify every activity.
