NO-JIRA: Add static.Logger() so new code can use non-static patterns.

[alanconway]

Add static.Logger() so that the static logger can be passed as an argument.
Allows old code using the static log pattern to be extended with new code using log argument passing.

I'm not sure if we should add this, need to think about this a bit.

In a pinch you can already use the return value of V(0) to get a copy of the static logger instance.

static.V(0) is equivalent to the proposed static.Logger() so no need for this.
