FEATURE: Add fromClassAndMethodName() to LogEnvironment

[kdambekalns]

This does some code cleanup and adds a new method fromClassAndMethodName($className, $methodName) to the LogEnvironment.

It be used like this:

LogEnvironment::fromClassAndMethodName(__CLASS__, __METHOD__)

and will return useful data – as opposed to LogEnvironment::fromMethodName(__METHOD__), which only works for static methods (SomeClass::someMethod or closures).

Why is this a task and not a new (tiny) feature?
