Adding Handlers and Filters

Adding handlers and filters to loggers is now push!(logger, Union{Handler, Filter}) (vs add_handler(logger, handler, name)). Similarly, you can now add filters to handlers can also be done with push!(handler, filter).

Logger Hierarchy Propagation

Propagation through the logger hierarchy has changed significantly. Previously, when logger.propagate == true (default) log records would always propagate to parent loggers. This approach made it easy for log records to propagate up to the root logger's default handler, but made it more difficult to silence noisy loggers. Now, a record must pass all filters for a child logger before the record will propagate up to its parent logger. This approach makes it easier to silence child loggers (just change level on the logger), but it is slightly harder to get debug, info and notice messages from child loggers (either recursively update all loggers in the hierarchy or add a handler to the child logger directly).

Other Changes

The API was also significantly changed to be more julia. Mutating methods now end with an ! and multi-word function names no longer use _.
