Add user-friendly explanations of current workflow keywords on a ticket

[johnbillion]

When a ticket is closed on a completed milestone, a helpful message is shown at the bottom of the ticket:

It would be neat if similar messages were displayed on tickets which have the following keywords:

• needs-testing
• needs-refresh
• needs-patch

The intention is for inexperienced users to see a helpful message that clearly states the next action that needs to be taken on a ticket. For example, the message for a ticket with the needs-refresh keyword could be:

This ticket has a patch that is out of date and no longer applies cleanly. The existing patch needs to be updated, or a new patch needs to be written. Click here for information on how to write patches.

Ideally the messages would stand out more clearly, possibly in the same style as the "Are you in the right place?" message at the top of the new ticket screen.

I just noticed that this functionality is already in place for the reporter-feedback keyword, but the message is hidden away right down the bottom near the Submit Changes button.
