Display additional object properties

[gzip]

It would be nice to see the various object properties in a panel. Info such as x, y, width, height, walk to x/y, player face direction, and preposition. The UI should anticipate support for editing later on. Info like rom offest and payload size might be helpful.

This is mostly done but object ID, walk to x/y, and player face direction are still pending.

Displaying the object name in the panel would also be nice.
