Replace "tts" with "voice" in suggestion text

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run autocrack
2. It says: "Looks like you have festival installed. Have you tried the tts 
option?"
3. Oh, how cool, no, I haven't. Let's try it:
4. Run autocrack --tts, or autocrack -tts, or autocrack tts
All fail because no such option exists.

So I have a look at the --help and find out the option is actually called 
"voice", not "tts". Then why not change that text to

"Have you tried the voice option?"
