Study simplifies to link=, more test cases
Factor out `result_within`

A common pattern in some SeleniumTest methods is to wait for a certain
block of code to evaluate as true-ish, up to a timeout in seconds. This
commit pulls out that code into a new support method `result_within`.
Spec tests included.
Change `== nil` to `.nil?`
Tidy things up, add globify tests
Add `failed_within`, counterpart to `result_within`.
