Changes relevant for Docker since 0.6.6 are (most other changes are hooks and
options for formatters):
* Debugging color output changed to gray.
* Don't quote the number 9 when it's by it self (i.e. `omg=9` instead of
`omg="8"`, this was the case for all other numbers)
* Performance is better when running a high logging level with lots of low-level
logging.
* Minor internal refactoring and more tests.
