* Minor syntax tweaks to make the code Python 3 compatible
* Fixes for various NumPy warnings/errors, either due to use of "float"
where "int" is required, or domain errors on log functions
* Replaced the use of the obsolete Python-2-only scikits.talkbox
library with a compatible LPC implementation from the Conch project
* Documentation update to indicate that an old version of "rnn" is
required
* Invoke Lua scripts via "luajit" directly, instead of going through
the "th" frontend (to reduce the dependency footprint)
