Correct PATH in converter_wav_text

[jeff1evesque]

The following changes don't matter much, since rc.local, our apache2 file that loads our bash_loader file, is called at the end, which should mean the PATH variable should mean that our PATH variable has been well defined, and constructed. But, we proceed anyways, to get into the habit.

We need to change:

# allow 'pocketsphinx_continuous' command
PATH=$PATH://usr/local/bin/

to the following:

# Pre-Pathing: allow 'pocketsphinx_continuous' command
PATH="/usr/local/bin:$PATH"

This ensures we add our PATH variable to the beginning of the $PATH environment variable.
