UI is now bundled with the script

Errors no longer get automatically logged. `ready` is now a function so that scripts can try to fix validation issues & retry

Config edits now get saved

Switched to updated tree-frame URL. Also started using eslint so re-wrote for compliance

$config.ready no longer continues to hold a rejected promise after $config.reset is called & succeeds

Frames are now paired with the script that opened them via KEY_TREE ids

Prevents config use until a validated tree is returned by an iframe. An iframe is opened on $Config instantiation & isn't ever closed unless validation fails. Changed `init` method name to `ready`.
