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.
