direct mode support

[William Hubbs]

All,

if you are using speakup from git, I just pushed a commit which adds
direct mode support to all of the synthesizer drivers.

The way it works is you will find a file
/sys/accessibility/speakup/synth/direct which by default has a value of
0.  If you set this to 1, speakup will do no text processing at all and
will send text directly to the synthesizer.

Once that is turned on, the way to control which punctuation is
pronounced is by using the /sys/accessibility/speakup/synth/punct file.
The other punctuation settings do not take affect in this mode.

Let me know what you think.
