Clock-16 does not speak on Fedora 18

[quozl]

(sugar-activity:805): GStreamer-CRITICAL **: gst_element_factory_make: 
    assertion `gst_is_initialized ()' failed
espeak_Synchronize() failed, maybe error when opening output device

Regression introduced ​fac8b9b.

In _do_speak_time() the exception handler is active because Gst.parse_launch() raises GError: no element "espeak". There is no GStreamer element for espeak installed. As a result speaker.py is called.

Speculation: espeak_cmd.py from the Speak activity may be a better method. It writes espeak output to a pipe which is then passed to GStreamer.

Was a problem with espeak command in F18.

Running:

espeak "hello world"

in the terminal gives a error about not be able to open the audio device.

Implemented a solution using tts in the sugar toolkit (Need Sugar 0.104)
