Strip leading and trailing spaces in URL validator

_Originally opened at !2914 by @evuez._

It makes URLs in webhooks valid even if they contain leading and/or trailing spaces.

Spaces are hard to notice in input fields, this helps users by accepting leading and trailing spaces in webhooks URLs.

Move "I should see Crowd login form" feature to a view spec

We were doing all kinds of code gymnastics to "enable" Crowd in the
feature spec and this would sometimes cause a transient failure.

Really what it's testing is if the Crowd login form shows when Crowd's
enabled, so this is much better suited to a view spec.

Reformats confusing '[named here]' section for 3rd party code attribution

Weird formatting originally. Which of the following is the proper format for attribution?

1. Submitted on behalf of a third-party: [David Alexander]
1. Submitted on behalf of a third-party: [[] David Alexander]
1. Submitted on behalf of a third-party: [] David Alexander
1. Submitted on behalf of a third-party: [[ David Alexander ]]
1. ... _etc._

With this change, it allows for either of the following formats:

1. Submitted on behalf of a third-party: [David Alexander]
1. Submitted on behalf of a third-party: David Alexander
