Noteworthy changes in this release

For this release Bert Frees has been hard at work to clean up the code base. He fixed a few bugs one of which was causing memory corruption. Others have contributed corrections to braille tables or even provided new tables. For example there are now tables for Tshivenda and for Russian contracted braille.

I'd like to thank everybody for helping to bring liblouis forward.
