Use the wikified changeset log message in order to compute the ETag of a changeset view. Fixes #3116.

Small fixes for the `IContentConverter`s in the ticket subsystem:

* use `trac.ticket.Ticket` instead of `trac.ticket.model.Ticket`
* use `trac.ticket.Query` instead of `trac.ticket.query`
* use quality `8` instead of `9`, so that it's easily possible for
the user to force the usage of a custom converter, while staying
in the 0-9 range.
* make the conversion tests more platform independant (both modified
tests failed for me on Windows)

PermissionPolicy: Merged log:trunk@...:3307

Added unit tests for ticket content conversion.

`s/get_conversions/get_supported_conversions/g`

''Work in Progress'': Added `mimeview.api.IContentConverter` which provides
generic MIME content conversion. Converted existing query and Wiki format
conversions to use this API, as well as adding conversions for tickets to CSV
and RSS.

''TODO'': Replace `mimeview.api.IHTMLPreviewRenderer` with this API, add
conversions for milestone view.

oops, typo in r3303

Added direct access to the list of attachments.

{{{
/attachment/<parent_type>/<parent_id>
}}}

At the same time, simplify the attachment related code
in the ticket and wiki module.

An authenticated session couldn't be created if there were no corresponding anonymous session.
Now the 4 possible situations (auth session already there or not,
anonymous session already there or not) are checked for, and correctly handled.

Closes bug #3154.

Follow-up to [3300]: bump up DB schema version.
