Prevent deletion of a version of a Wiki page from the middle of the history. Only deletion of the latest version is possible. Related to #1114.

Better ''title'' for the Wiki diff view: now it has direct links for viewing the content of the old and new versions being diffed.

More robust traversal of the history of a Wiki page using ''Previous Change'' and ''Next Change'' links: gaps in the sequence of versions are now correctly handled.

Quicker access to last change of a Wiki page, from the Wiki view.

The ''Page History'' can still be reached from that last change.

Related changes include the renaming of the ''Title Index'' and
''Recent Changes'' links to ''Index by Title'' and ''Index by Date'',
in order to prevent any confusion between ''Recent Changes''
and ''Last Change''.

Closes #2165.

On the ''Search'' page, the quickjump now doesn't immediately redirect to the corresponding resource. Instead, a normal search for the term is performed and a special ''Quickjump to ...'' entry is inserted at the top of the result list. The quickjump from the search form in the header works as usual. Closes #1269.

Refactored a bit the e-mail ticket notifications,
so that the Ticket URL links to the relevant change, like the
timeline entry does.

I also took this opportunity to fix the last usage of self.env.abs_href
in the code.

Close #3277, add two new buttons to the edit area:
* new paragraph button
* line break button

Session-backed query memory wasn't being timed out as intended... it is now invalidated after an hour.

SpamFilter: Deletion of BadContent page revisions is now trapped, and perform a
simple binary content exclusion check in Akismet plugin.

Move wiki/ticket/attachment change listener hook callbacks to after the
transaction is committed, thus preventing exceptions in listeners from breaking
transactions.
