Patch to make orca explicitly set speech-dispatcher's priority to message.

If a user uses orca with speech-dispatcher for speech output then the way speech interrupts current speech could be affected if the default priority of speech-dispatcher were changed.

As an example output with priority message or important will not be interrupted by output of the same level but the later output will be queued to be output after the current message. If the priority level was text then other messages of level text will interrupt the current speech. Also note that messages of a higher priority will interrupt messages of a lower level (eg. message can interrupt text, important will interrupt text and message).

As orca uses the default level, then if the user were to change this it could affect orca's output. Also if the developers of speech-dispatcher were to change the default level this may impact on orca (eg. looking at the speechd.conf file and from what I have heard on the speechd list the default level might be meant to be text although currently it is a higher level, I don't know if what I have heard is wrong).

The solution seems to be to get orca to explicitly set the priority level it relies on. I have a patch for this to set it to use priority message which seems to be the correct level from what I understand.
