Removed 'Subclassing Context: Custom subclasses' from docs/templates_python.txt because the same thing can be accomplished using DjangoContext processors

Subclassing Context: Custom subclasses
--------------------------------------
Feel free to subclass ``Context`` yourself if you find yourself wanting to give
each template something "automatically." For instance, if you want to give
every template automatic access to the current time, use something like this::
from django.core.template import Context
import datetime
class TimeContext(Context):
def __init__(self, *args, **kwargs):
Context.__init__(self, *args, **kwargs)
self['current_time'] = datetime.datetime.now()
This technique has two caveats:
* You'll have to remember to use ``TimeContext`` instead of ``Context`` in
your template-loading code.
* You'll have to be careful not to set the variable ``current_time`` when
you populate this context. If you do, you'll override the other one.
