Add functionality to TTS

[IsemicolonI]

TTS will work only when one word is selected and not work if more than one word is selected.

[neoOpus]

TTS works without having anything selected, just by pointing and using the trigger key if you've set one, it will read the whole sentence (or paragraph), it is not meant to be something that read long text, check your settings and set "Text Detect Type" to "Sentence" or preferably "Container"
