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.

Benefit to Sugar

Text to speech is a good feature to kids, when they are learning to read, and to kids with disabilities

Scope

The change is isolated.

UI Design

I propose use de default language now, and only expose controls to set pitch and velocity. In a later change, we can implement have more than one language enabled, and a switch to change it.

The UI will be a device in the frame, with the needed controls in the palette.
