Fix wiki model unit tests to work under Python 2.3.

We can't use the MemoryHandler log handler since this handler keeps references to logged exceptions for a long time. This caused problems for the db connection pool.

* improve `cc` list changes in email notification
* reformat `cc` list field on ticket change:
* remove duplicates
* use a comma char. as email address separator

Fix for bug in config saving.

As setting the svn:mime-type property in r3237 worked as expected, do it also on trunk.

Follow-up to r3236, force the wiki-tests.txt file to be displayed as UTF-8 (hopefully)

Wiki headings containing some special characters could
trigger an `UnicodeDecodeError: ... unexpected end of data`.

For example, the character `LATIN SMALL LETTER A WITH GRAVE`
is encoded in UTF-8 using the 2 bytes sequence `'\xc3\xa0'`.

Depending on the current locale, the `splitlines` function
used in `wiki_to_oneliner` might interpret the single byte
`'\xa0'` as a `NO-BREAK SPACE` (in most of the ''iso-8859''
and a lot of the ''cp'' encodings).
This splits the utf-8 encoded string right in the middle of
a two bytes sequence, which will later trigger the above exception.

Therefore we temporarily use `unicode` objects before
doing the `splitlines`.

Of course, this is only relevant for [milestone:0.9],
as since [milestone:0.10], `unicode` objects are used
internally.

Fixes #3058.

Fix the ordered list regex. Only one letter is allowed before the dot,
e.g.
{{{
a. item 1
b. item 2
}}}

but not:
{{{
This is not a numbered
list. Just a small quoted
paragraph.
}}}

Still, roman numbered lists should work
{{{
i. item 1
ii. item 2
iii. item 3
}}}

Follow-up to r3162.
