[1.45.43]

Added runtime detection of pulseaudio, with fallback to portaudio if pulse is not running.  Use build option "AUDIO=runtime" in the makefile.

Phoneme programs. Added condition "isTranslationGiven" to test whether a phoneme has been specified explicitly for a word in *_list.

*_rules files.  Suffix rules are now considered only if there is a previous vowel in the word.
