Use unicode internally for the attachment filenames. Could fix #2981.

Follow-up to r3101: in TracAdmin `wiki load/import`, we should assume that the wiki files are using the UTF-8 charset.

Unicode fixes for TracAdmin (import from and export to UTF-8 encoded files)

Follow-up to [3097]: skip resources that don't have all their requirements available, instead of aborting.

Fixed the file viewer in the TracBrowser module.

There was some confusion between the requested path/rev and
the last modified path/rev, which produced errors when viewing
a file which had just been copied. This fixes #2949.

Also, when no revision has been specified, the TracBrowser
don't artificially add the latest revision to its links.
This makes it possible to browse the repository to its
latest state, unless explicitely making a revision ''sticky''
by specifying it in the ''View revision: '' form.
That fixes #987.

Fix support of space characters in paths. This concerns `mod_python` when the `TracUriRoot` directive is used. Closes #2864.

Applied patch for #2899. Thanks pacopablo.

Some follow-up to r3092 and r3094 for the TracChangeset ''diff'' format (either old_node or new_node could be None) and ''zip'' format (better comment)

`trac.util.markup.Fragment` objects can be directly attached to the HDF
