add option `[wiki] render_unsafe_content` to enable the use of unsafe HTML in the HTML processor (fixes #4419)

use more specific mimetypes for CSV and TSV export of reports in consistency with the query module (fixes #2669)

add `separated` function for augmenting sequences with a separator token, or `None` on the last item and use it in the `query.html` template

Follow-up to r4406: forgot to rename one occurrence of `date` to `change.date`. Fixes #4420.

TracMercurial: let the oldest_rev be the nullid

TracMercurial: ported r4465 from the 0.11 branch

mimeview fix: pygments_renderer change to support rework in Pygments:changeset:2479 -- closes #4421

TracMercurial: a few error handling improvements
- don't give an internal when browsing an empty revision (fixes #4410)
- correctly show the oldest revision to be the nullid in this case
(viewing the nullid revision requires either the r4464 fix or having a non local timezone set)
- use !NoSuchChangeset and !NoSuchNode exceptions where needed
- bumping the revision number from 0.3 to 0.11.0.1

datetime fix: make the !LocalTimezone more robust when old dates are specified.
