Fixed #24257 -- Corrected i18n handling of percent signs.

Browse Source 
Refactored tests to use a sample project.

Updated extraction:
* Removed special handling of single percent signs.
* When extracting messages from template text, doubled all percent signs
  so they are not interpreted by gettext as string format flags. All
  strings extracted by gettext, if containing a percent sign, will now
  be labeled "#, python-format".

Updated translation:
* Used "%%" for "%" in template text before calling gettext.
* Updated {% trans %} rendering to restore "%" from "%%".

whitespace by default. This can be disabled by setting the new
:attr:`~django.forms.CharField.strip` argument to ``False``.
* Template text that is translated and uses two or more consecutive percent
signs, e.g. ``"%%"``, may have a new `msgid` after ``makemessages`` is run
(most likely the translation will be marked fuzzy). The new ``msgid`` will be
marked ``"#, python-format"``.
* If neither :attr:`request.current_app <django.http.HttpRequest.current_app>`
nor :class:`Context.current_app <django.template.Context>` are set, the
:ttag:`url` template tag will now use the namespace of the current request.

"""
Helper script to update sampleproject's translation catalogs.
When a bug has been identified related to i18n, this helps capture the issue
by using catalogs created from management commands.
Example:
The string "Two %% Three %%%" renders differently using trans and blocktrans.
This issue is difficult to debug, it could be a problem with extraction,
interpolation, or both.
How this script helps:
* Add {% trans "Two %% Three %%%" %} and blocktrans equivalent to templates.
* Run this script.
* Test extraction - verify the new msgid in sampleproject's django.po.
* Add a translation to sampleproject's django.po.
* Run this script.
* Test interpolation - verify templatetag rendering, test each in a template
that is rendered using an activated language from sampleproject's locale.
* Tests should fail, issue captured.
* Fix issue.
* Run this script.
* Tests all pass.
