Target page entries used to exist for each user
that was notified for an event. They were
removed as the notifications were marked as read.
Now they remain so that the association between
pages and events can be used for moderation
regardless of the notifications read status.
This patch removes everything about
echo_target_page.etp_user from sql and php code.

To allow individual notifications to be
marked as read/unread or moderated,
bundles are created by grouping associated
notifications when they are fetched for display
instead of when they are created.
From a product perspective, this change doesn't
introduce moderation or expandable bundles but
it counts each individual notifications.
For instance, the bundled notification
"3 new topics on PageA" now counts as 3
notifications.

Notification timestamp is generated in MW format (YYYYMMDDHHMMSS)
inside the model and saved to the database in db specific format,
We need to convert it back to MW format when loading the data
from the database, it just happens that MW format is the same
as MySQL timestamp format
