Fixes a freeze when opening the 'Create Object' panel

[SabreML]

About the pull request

Removes the long freeze when opening the 'Create Object' interface through the game panel.
This was caused by line 40 of create_object.html, which attempts to fill the object list with every subtype of /obj when the interface is first opened. The "fix" was just removing that line.

cmss13/html/create_object.html

Lines 33 to 42 in 0b13392

	<script language="JavaScript">
	var old_search = "";
	var object_list = document.spawner.object_list;
	var object_paths = null /* object types */;
	var objects = object_paths == null ? new Array() : object_paths.split(";");
	document.spawner.filter.focus();
	populateList(objects);
	function populateList(from_list) {

This does mean that the user has to search for a type before anything shows up, but I would consider that a pretty minor trade-off.

I also increased the window size so that the 'Spawn' button is on the screen by default, removed a couple of empty values, and added some spaces so that the HTML code lines up a bit more with the final UI.

Explain why it's good for the game

Fixes a 30ish second freeze for admins. (Give or take a bit, but it's still long either way.)
