config panel shows loaded config

[peterv959]

I adjusted as little as I could to get the loaded emulator config values to display on the config panel. I sorted the keys. When the values are themselves javascript objects (i.e. a dictionary or a list) they are displayed on separate lines within the table row. I did not sort those keys. The argv parameter displays with the list indices as the "key." The colors parameter just has the key and value on each line. I contemplated making them tables within the table but opted not. Nor did I go to the trouble to recurse. I can't imagine the need for further nested objects. It wouldn't be hard to do but seemed like overkill. I hope you'll find it doesn't look much different than what you might have written. I used it as a learning exercise for Vue.
