New features for speakup

[David]

It's been awhile since I contributed nine years!
I have a David modified version for 4.5.0 kernels which has the following
added features. Per screen synth variables so Darlene and I don't fight
over punctuation, rate etc. A variable can be set to multi so each
console can have its own settings. Also multiple cut and paste buffers.
One is local, to each console and three global ones like the current cut and
paste buffer. Also for those of us in software where people like code
properly indented, a say indent feature which says how far the line is
indented. Also you can read the contents of any of the paste buffers
in case you forget what is in them. Also changed rate/pitch variables
so instead of them being a number, the words per minute or absolute
pitch values are spoken.  The next thing I am working is to get away from
requiring an on-board uart and instead, use any serial/usb device
available in the initial dev-fs. Yes, it will use evil writes to kernel
space devices and the purests will stone me maybe. But on-board uarts are
becoming rare and pci-express serial cards ought to be useful.
