Switch from ClearSilver to Genshi

I'd suggest taking a look at the TracWikiPrintPlugin. We may want to deprecate this plugin in favor of that one.

(In [11262]) Refs #6243:

• Replaced some deprecated calls to the Trac API.
• Cleaned up imports.
• Fixed incorrect indentation.

Useful resource: t:TracDev/PortingFromClearSilverToGenshi.

(In [11469]) Refs #6243:

• Fixed indentation.
• Removed un-needed imports.

(In [11472]) Refs #6243:

• Fixed indentation.

(In [11474]) Refs #6243: Tagged trunk with dev.

At least list ClearSilver as a requirement and provide some guidance on how to get it working. Neither the ClearSilver page not EdgeWall's mention of it says much more than "download it".

(In [11507]) Refs #4043, #6243:

• Removed some needed imports in [11469].
• When wiki page is created from the Admin panel, the page variables in not passed as a argument in the request. We'll have to find some other way to get it.

Replying to ChrisNelson:

+1.

On Debian:

$> apt-get install python-clearsilver

That runs OK, but makes no changes on Trac's behaviour. So, i did this other thing:

$> easy_install clearsilver
install_dir /usr/local/lib/python2.6/dist-packages/
Searching for clearsilver
Reading pypi.python.org/simple/clearsilver/
Reading clearsilver.net/
Best match: clearsilver 0.10.1

sh: configure: not found
sh: make: not found
error: clearsilver/rules.mk: No such file or directory

$>

Then, this other command:

$> pip install clearsilver

    Complete output from command python setup.py egg_info:

Will post here any update. NOTE: edited some URLs because trac-hacks didn't let me post the raw log saying that, as it had some URLs, it could be spam.
