An exception raised during the rendering phase (e.g. wiki formatting) would be reported by the error.html template but without the default styling. We make sure to restore the links them if needed.

HTTPException had issues with Python 2.5: we happened to use the `.message` property to store our error message, which could eventually be some markup. This got overriden by the `.message` property of `BaseException`, introduced in 2.5.

Fixes #5066.

Ticket #2821: Merge 5386,5388-5389,5391-5392 from trunk.

0.10.5dev: ported r5392 (''fix writing of trac.ini.sample, #5303'')

Write the `trac.ini.sample` using the same method as the one used for writing `trac.ini`, so that the ordering of their content is kept the same, which facilitates comparison and diffing. Thanks to techtonik for the patch. Fixes #5303.

TracAdmin: add a `resolution` command, with the standard subcommands for manipulating enums. Together with r5384, this fixes #905.

SpamFilter: encode content to utf-8, then to base64 before storing it in the spam log. Fixes #4087.

Woops, undo unrelated change...

Error message template: when rendering !TracError messages containing markup, we need to take care not to embed a <p> within the <p class="message">.

Also, we take this occasion to do some html->tag changes, clean-up some import statements and update a few copyright dates.
