Fix bug, use of the command-line  "espeakedit --compile" produced phoneme data
in which vowels started at full amplitude instead of gradual increase.

Fix bug:  SSML <break time=""> with values greater than 23 seconds were ignored
due to arithmetic overflow.

Phoneme definition files:
Added new function:  ChangeNextPhoneme().

Language changes include: da, en, fa, gu, hu, it, nl, pt, ta

Started new language: eu (Basque).

*_rules files:
Allow $p_alt1, $p_alt2, etc in pre-conditions.  The rule matches if the
characters before the current point in the word occur as an entry in the
*_list file with the corresponding $alt attibute.

Added condition $list.  This is similar to $p_alt etc, but examines
all words in the *_list file which don't have the $only attribute.
