added definition for  phoneme l in ph_italian

updated dictionaries, march 2016

This can occur in cases where the voice is not found, or
espeak_ng_Initialize is called more than once.

This reverts commit 6d9b9c4db6.

This is handled by calls to espeak_ng_Cancel/espeak_Cancel and
espeak_ng_Terminate/espeak_Terminate.

Removing these calls do not impact on the behaviour of the program
and simplify the wave.h API.

These calls are used to pre-emptively exit when writing audio
data. This is also handled within dispatch_audio. The difference
is that this callback could allow espeak to cancel quicker. In
practice it does not make much difference.
