There are small typos in:
- aksetup_helper.py
- doc/types.rst
- examples/black-hole-accretion.py
- pyopencl/__init__.py
- pyopencl/cl/pyopencl-random123/array.h

Fixes:
- Should read `unconditional` rather than `uncondtional`.
- Should read `transferring` rather than `transfering`.
- Should read `recipes` rather than `recipies`.
- Should read `preferred` rather than `prefered`.
- Should read `corresponding` rather than `correpsonding`.
- Should read `arrays` rather than `arrrays`.

Closes #500
