Subject: Centralize settings for executable based TTS systems.

The configuration values for executable based TTS systems is stored in member
variables. Instead of reading them multiple times provide a function for that
and move searching the executable to the loading function.

Previously the executable was only searched in the path when opening the TTS
configuration. Having this in the loading function removes that unnecessary
step in case the TTS is in the path (and doesn't require additional
configuration).
