Installation breaks with SyntaxError: Non-ASCII character '\xc3' in file

[damaxl@…]

There is an issue with plugin.py at Rev: 7790. When preparing the egg file with python setup.py bdist_egg an error occures:

Traceback (most recent call last):
  File "setup.py", line 7, in <module>
    from tracnumberedheadlines.plugin import __revision__ as coderev
  File "/download/trac/numberedheadlinesplugin/0.11/tracnumberedheadlines/plugin.py", line 22
SyntaxError: Non-ASCII character '\xc3' in file /download/trac/numberedheadlinesplugin/0.11/tracnumberedheadlines/plugin.py 
on line 22, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

There is a german 'Umlaut' character 'ä' in the file. Change it to an 'a' and everything works fine.

Made SVN date and rev unicode strings. The date can include non-ascii characters on non-english installations. This should fix #7005.
