Cache wrapper not working properly

[smant]

1. Since April 5 PAGE_CACHE_LOCATION setting not used anywere
2. With Django 1.8.6 code on pages/cache.py always select 'default' cache

1 + 2 + locmem cache as default + several uwsgi workers = hard to resolve issues with editing

This one looks bigger as CMS is invalidating cache but at that moment it has access to only 1 cache location.
It need to know when cache was create and update if outdated.

The cache has been designed with memcache in mind: a single point of truth for cache. If you are using memory cache in several processes it will not invalidate properly.

I updated the documentation and fixed the bug with the cache:

Thanks for the report. Could you check this is all working? I would like to unit test this but it looks like it might be an difficult task.
