New Version of WAT

I spent some time fiddling with the ol' wobble analysis tool today. Periodicity is actually useful now. You can zoom in on individual nights. I got rid of the flow limitation logic as it's outside the scope of this project. The old version is still available for those who prefer it.

It's now more explicitly targeted as a high loop gain detector. There's plenty of other great tools for flow limitation.

Let me know what you think!
