Endless wordlists

[dcraig327]

Consider adding a Scripting feature -endless to allow tt to operate when the worldlist has been exhausted.

The use case: I had to choose an email handle and questioned which of the presented two options were faster to type. tt came to the top of brave's search results. Yet it's not clear if this is possible.

Created two files, each containing the email to test. Ran tt -t 10 email1.test which ran once and quit. I don't know if this is possible with tt without filling a file with the same phrase multiple times.
