[3.x] Correct jslint errors

[Condor]

I thought it would be a good idea to run jslint on the Ext codebase to check for dubious code.

I added the following lines to ext-all-debug.js (latest SVN build):
/*jslint adsafe: false, bitwise: false, browser: true, cap: false, css: false, debug: false, eqeqeq: false, evil: true, forin: true, fragment: false, immed: false, laxbreak: true, newcap: false, nomen: false, on: false, onevar: false, passfail: false, plusplus: false, regexp: false, rhino: false, safe: false, sidebar: false, strict: false, sub: true, undef: false, white: false, widget: false */
/*global Ext: true */
and executed jslint.js using Rhino:
java -jar js.jar jslint.js ext-all-debug.js >warnings.txt
(I modified jslint.js to remove the 50 warnings limit)

Unfortunately Ext contains a few code segments that can't be parsed by the jslint parser (these are not errors, just unsupported syntax):
id : function(el, prefix){
return ((el = Ext.getDom(el) || {}).id = el.id) || (prefix || "ext-gen") + (++idSeed);
},
elasticBoth: function (t, b, c, d, a, p) {
...
p = p || (d * (0.3 * 1.5));
...
createListener: function(fn, scope, o){
o = o || {}; scope = scope || this.obj;
...
fire : function(){
...
return (ret = me.firing = FALSE);
...
"first-child" : function(c){
...
for(var i = 0, ci; ci = (n = c[i]); i++){
...
},
"last-child" : function(c){
...
for(var i = 0, ci; ci = (n = c[i]); i++){
...
},
replaceWith: function(el){
...
return (Element.cache[me.id] = me);
},
request : function(o){
...
return (me.transId = Ext.lib.Ajax.request(method, url, cb, p, o));
...
},
checkModifiers: function(config, e){
...
key = keys[i]; val = config[key];
...
},
onLayout : function(ct, target){
Ext.layout.VBoxLayout.superclass.onLayout.call(this, ct, target);
...
var totalFlex = (totalHeight = 0);
...
onLayout : function(ct, target){
Ext.layout.HBoxLayout.superclass.onLayout.call(this, ct, target);
...
var totalFlex = (totalWidth = 0);
...
setRawValue : function(v){
return (this.el.dom.value = (Ext.isEmpty(v) ? '' : v));
},
validateValue : function(value){
...
return (blank = false);
...
},

Can these jslint errors be fixed? And after these are fixed, can somebody look at the output of jslint and correct some of the warnings?

I've got the local copy running, I think what I'll do is if I'm looking at a file I'll run JSLint over it, eventually I'll cover most things...
