Use of SendNewAssigneeNotification inconsistent

[aliciam]

SendNewAssigneeNotification is called when saving an existing issue and a new assignee is specified. This is in addition to sending any update notification if the user is also subscribed to the issue. However, when creating a new issue, although the newly assigned person is added to the list of notifications and sent a standard "new issue" notification, they are not sent a "you have been assigned" notification. This notification is important for two reasons:

1. people have filters on their email inbox, and are likely to want to highlight/prioritise/filter differently any issue they have been assigned to.
2. when adding finer control over notifications, even if one is subscribed (by virtue of being assigned) to an issue, they might not necessarily chose to receive added issue notifications, but still wish to receive all notifications of their assignment to issues.

I am fixing this in my working copy as I'm adding finer notification control. However, it is unclear whether I should allow the creator of the issue to override the wishes of the assignee and prevent them being notified.

Change required is in CreateIssue.aspx.cs
