patch review: patch 51377 for bug 314559: Be able to scale pictures when
sending an e-mail

Compilation:
- this patch no longer cleanly apply against up-to-date CVS. Things to modify
in SendEmail.cs:
   - replace 2 occurences of IPhotoCollection by IBrowsableCollection
   - replace all occurences of photo.DefaultVersionPath by
photo.GetVersionPath(photo.DefaultVersionId)

Add attachment:
- is working with Evolution (2.6): the temp image can be removed before sending
e-mail. As Larry suggested, we need to start a timer and then remove the image
- is *NOT* working with Thunderbird at all. A new mail window is opened, but
without any attachment

UI:
- for evolution and with a timeout, remove the dialog.
- when the mail is sent, you always have a dialog with 2 buttons: 'cancel' and
'send mail'. This dialog should disappear.

Missing feature:
- when exporting full-size, rotate according to EXIF (optional)

Without this patch, the Send Mail command is useless !!!
