Customizing notification subjects about bugnet

[aliciam]

I've just implemented something along these lines, although the bugnet administrator must set these up directly in the resource file at present.

Currently Notification Subjects are stored in Notifications.resx and there is only a single subject key for an updated issue notification (IssueUpdatedSubject). If you want to specify something like NewStatus you'd have to know that it was the Status that was changed and sent that value to

I've kept the single IssueUpdatedSubject (for now) and created a set of priority fieldnames to use to select the IssueHistory that is most salient to the user. Then a generic FieldName, OldValue and NewValue can be used in the subject.

e.g. IssueUpdatedSubject = Issue {IssueId} "{IssueTitle}" {FieldName} changed to "{NewValue}"
where several fields have been changed, including the status, would result in the subject line (given the appropriate data):

Issue BN-42 "Meaning of Life" Status changed to "Solved"

See my commit of those changes
