Any iterator whose item is convertible into `Line` can now be collected into `Tabs`. In addition, where previously `Tabs::new` required a `Vec`, it can now accept any object that implements `IntoIterator` with an item type implementing `Into<Line>`. BREAKING CHANGE: Calls to `Tabs::new()` whose argument is collected from an iterator will no longer compile. For example, `Tabs::new(["a","b"].into_iter().collect())` will no longer compile, because the return type of `.collect()` can no longer be inferred to be a `Vec<_>`.
