Potential bug and fix for ui.resizable.js

Potential bug and fix for ui.resizable.js


Someone with more experience than me should confirm if this is the
valid fix or if it is just fixing a symptom of some other problem.
While the old line worked for Firefox, I'm surprised I haven't seen
any other mention of this as it was a show stopper for IE7.
Old line:
    for(var i in this.options.modifyThese) {
Error message on line "c[0].css({...})":
    Microsoft JScript runtime error: '0' is null or not an object
The value of i was a string "indexOf". As far as I could tell
modifyThese was not being used as a associative array so the "var i in
object" syntax wasn't a valid way to loop through the array.
Changed to:
    for(var i = 0; i < this.options.modifyThese.length; i++) {
I've tested this change in Firefox and IE7 and both work as expected
with the new line.
Use at your own risk...
