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.
