Voice file generation: * Significant speedup of SAPI5 voice generation by running lame and wavtrim from inside the VB script instead of the perl script, avoiding the large overhead of process generation within cygwin. Added proper synchronisation between perl script and VB script as the pipes are buffered. * Make wavtrim work as intended (threashold wasn't passed). * Set correct SVN properties for the VB script.
