Adding a second logging target doesn't register

[johncblandii]

Steps:

1. Initialize Swiz with TraceTarget as the only logging target
2. Elsewhere in my app, after some initialization/stage updates, I add a TextAreaTarget [custom] through a loggingTargets.push(...).

Results:

1. TraceTarget is only target to get the traces

Fix:
Instead of using push(), reassign the loggingTargets to a new array.

swiz.loggingTargets = [newTargetHere];

This has a downside of keeping the old target as well as the new one though. For this instance, I don't care but I could see where I might want to get rid of an old target but that doesn't seem to be happening.

Expected Results:
When I reset loggingTargets to a new array, I expect all old loggingTargets to be removed.

Notes:
I am aware of SwizLogger.addLoggingTarget(...). This is more about removing targets, which doesn't seem possible.
