test(rxBreadcrumbs): names, count, and main

This is to make rxBreadcrumbs easier to bring into apps that need to
assert breadcrumb status on a page. It uses the same approach that
rxPage uses to pull in the default element, since there's likely only
one on the page, and there's only a couple things that matter.

feat(Environment): Better ways to check for a valid environment

This addes the following methods to Environment:

  * isPreProd
  * isLocal
  * isUnifiedPreProd
  * isUnified
  * isUnifiedProd

For instance, rather than calling `'local' === Environment.get().name`
you can just do `Environment.isLocal()`

test(rxModalForm): Use `submitText` and `cancelText` in our demo page

We weren't testing that `submitText` or `cancelText` work on the
`rxModalForm`. This changes the demo page to use both of them, and
adds midway tests to confirm.
