2921	Add docstring to top of lib/extract.py file	seanh		"I think it couldn't hurt for this module to have a docstring at the top
of the file explaining what the module is for. I know from setup.py that
it's there to provide the extract_ckan() string extractor function for
Babel, but I think looking at the file on its own it's not so obvious.

Also a couple of other small fixes:

jinja2_cleaner looks like a helper function only meant to be used by
extract_ckan(), might make things clearer if it was called
_jinja2_cleaner(), just so it doesn't look like a public function the
module wants to export.

jinja_extensions seems to be a module-level variable that is only used
in one function, could be moved into the function, unless you think
there might be more functions that want it in future."	defect	new	awaiting triage	ckan 2.0	ckan				ckan	none
