Allow messages in groups to be resent

1. Go to the message tab in any group, http://next.dev.curriki.org/xwiki/bin/view/Group_TestingDashes--HelloWorld/Messages
2. For each message that you have editing rights there is an Edit link.
3. Select the Edit link.
4. The Edit link opens a page with the orginal message, plus the ability to add a comment or attach a file. http://next.dev.curriki.org/xwiki/bin/view/Messages_Group_TestingDashes--HelloWorld/SpecChangeonMessages?edit=1

5. Spec Change: Selecting Edit should only display the message not the comments or attach a file.
6. Spec Change: In addition, when in Edit mode, include the Send Information at the bottom, similar to what you see when you are creating a message. However, with one difference. The buttons on the bottom should be Cancel, Save, Save and Send Message
7. Spec Change: The to information should be pre-populated with any existing information if the message was previously sent. That is, when I created the message I chose to send it to just Joshua, when I edit, I should see that is who I sent it to last.
8. The user can now choose to resend the message:
9. If the user removes a person , group, etc off the "to" list, then resends it, the removed people will no longer see the message on the Message tab.

Joshua: The first message was sent out and member(s) will see it in their message list box. I now go in and edit it, and choose a different group of people to send the message to, the message now has new people associated with it, and the old group of people will no longer see that message in their inbox. Maybe, maybe not. Will the message need to track everyone who has ever had this message sent to? If I edited the title, will the first group of people see the change?
