* Avoid writing to log files during unit tests
* Translate PHPDoc of `record()`
* Move environment variable into `phpunit.xml` and use tabs for indents
* Add configurable log_level system setting
Minz_Log currently only distinguishes 'production' (errors and
warnings only) from any other environment (everything, including
debug messages), with no granularity in between.
Introduce an optional 'log_level' system setting (error, warning,
notice, info, or debug) that overrides the verbosity implied by
'environment'. It defaults to an empty string, which preserves the
exact current behaviour.
Fixes#7594
* Slight rewrite
