Add a configuration/settings page

[paulfalgout]

We should add a page that allows you to set what features are available when the inspector is running.

This would buy us a few things.
We could turn off some perf heavy options by default.
Rather than totally disabling problem features, we could list them as experimental (think feature flags)

Also if a particular patch or watch was totally broken with your particular app, you might be able to turn off a feature and still get something useful vs opening an issue and waiting on / helping it get resolved prior to having any sort of useful tool.

These settings could live on the big white page that currently houses the start button. And if it was a menu item it could handle where you would pause / stop the inspector.

Even this page could be split up into a basics and advanced, where essentially the basics are turning on and off features.. and for more advanced users you could turn off granularly individual patches.. (which could break or cripple a feature, but ideally you'd know what you're doing at that point)
