Housekeeping
Rename appender argument: :max-message-per-msecs -> :limit-per-msecs (backwards compatible)
BREAKING: Refactor Timbre for integration with clojure.tools.logging & logf macros

BREAKING CHANGES:
* Custom appenders that rely on the :more argument will no longer function correctly.
* Stacktraces are no longer automatically generated at the `log`-macro level, but are
left as an appender implementation detail. A :throwable appender argument has been added
along with a `stacktrace` fn.

MIGRATION GUIDE:
* :message is now a string of all arguments as joined by `logp`/`logf`. Appenders that
need unjoined logging arguments (i.e. raw arguments as given to `logp`/`logf`) should
use the new :log-args vector.

MOTIVATION:
The :more argument was always kind of manky.

By joining logging arguments at the `log`-macro level, we simplify appender
implementations and allow the use of different joining strategies like `logp` and
`logf`.

This approach also fits better with the `tools.logging` API, allowing a cleaner
Logger implementation.
