Document changes to the sharing features of Crucible

In Crucible 3.1 we have introduced the following changes to the way reviews can be shared:

• We removed the Email review link from the tools as it as providing the same content as Download review as text.

• We removed the Send reminder link from the tools menu to promote using the sharing button instead.

• If review is overdue the Share link says Send reminder instead and clicking on it opens the share dialog with the list of uncompleted reviewers pre-selected.

Those changes should be reflected in the documentation for the latest Crucible:

• Sending a review's comments via email should be amended: the user will have to download the comments as text via Download review as text and then use the generated txt file to send it via their own email client.
• Using review reminders should be changed in the Manual Reminders section and describe the new behaviour of the Share button.

Thanks,

Sten
