TTS: Refactoring

* Delete multiple empty rows
 * Make getVolume non-virtual and leave just the implementation
    in base class
 * Resolve warning about signed / unsigned comparison in
    gui-manager
 * Clear availableVoices when updating voices on linux
 * By default set language to transMan language on windows
    (if the transMan is available)
 * Remove freeVoices method from Windows ttsMan, it isn't needed
    anymore
