implement scoped <script type="dojo/connect"> system for declaratively created instances

[alex]

as discussed at length with owen and eugene, the system needs to augment programmatic widget and class instance creation with the ability to specify behaviors for instances in a declaration. These behaviors should be scoped correctly.

There is a bug in the committed code

suffic should be suffix ->

	function wireUpConnect(instance, script){
		var withStr = script.getAttribute("with");
		var preamble = "";
		var suffix = "";
		if(withStr && withStr.length){
			dojo.forEach(withStr.split(/s*,s*/), function(part){
				preamble += "with("+part+"){";
				suffic += "}";
			});
		}

oh - by the way, is it possible to get a personalised trac account ?

Alex and I discussed this feature a week or two ago. I think the conclusions were:

• change <script type="dojo/connect"> to <script type="dojo/method">, since users will be overriding methods more often than connecting to them.
• specify argument list like <script type="dojo/method" ... args="a,b,c">
• the specified methods get mixed in to the widget instance the same way as <button dojoType=... onclick="..."> gets mixed in
• if you need code to execute before the constructor then connect to preamble
