Also added something that was missing since long time: movie title (and eventually vehicle name) in page title, for the following reasons:
- not always the same "imcdb: movie vehicles" or "imcdb: details for vehicle" in the browser title bar.
- a more explicit title when searching a particular page in browser history
- better placement in Google and other search engines
But such change may lead to some new bugs

In movie search, when only one title is found you are redirected directly to that movie (using Javascript - I'll make that cleaner later).
