Switch to rfind_url for URL detection
This switches to rfind_url for detecting URLs inside the grid. Instead of expanding at the cursor position, the complete terminal is searched from the bottom until the visible region is left with no active URL. Instead of having the field `cur` publicly accessibly on the `DisplayIterator`, there are the two methods `DisplayIterator::point` and `DisplayIterator::cell` for accessing the current element of the iterator now. This allows accessing the current element right after creating the iterator. Fixes #2629. Fixes #2627.
