[timgates42]

There are small typos in:

• docs/caching/index.rst
• docs/overview.rst
• docs/query.rst
• lifter/caches.py

Fixes:

• Should read whether rather than wether.
• Should read translates rather than tranlates.
• Should read responsible rather than reponsible.
• Should read addressing rather than adressing.
• Should read across rather than accross.
