Fixes #196

Hi, I added a simple toggle for title hiding so that the titles aren't missing until the timeout elapses when the data fetching server is down. This would help out with issue #196.

I used showOriginalTitle because it was the most headache-free way (it didn't clash with other things). I'm not sure what onMobile is for here, so I tried to work around it. The locale is missing from this PR, but I assume you can add these two strings to the submodule pretty easily.

Let me know if this looks okay to you. Cheers

Hi, just commenting to resurface this addition. I'd love this to be an option that I can easily disable.
