mod_webmail: Update counts when messages in other mailboxes are read.

Include message flags in personal update set, so that if messages are
read in a folder besides the selected one, we get updated and reflect
the new unread count immediately. Previously, this was only done for
the currently selected folder, so it was common for users to click on
a different folder showing an unread count, only for that to get
updated at that point to reflect all the messages read in the interim.
By updating these counts in real time we provide a better user experience.
