Complete overhaul of the Ajax test suite, it's now passing in all browsers. In order to achieve this I had to fix a numbe
r of bugs in the suite itself, along with other random bugs that popped up. The following bugs were resolved along the wa
y: #1236 (.extend() keeps processing when it hits nulls), #1028 (.extend() now works recursively), #1080 ($.get no longer
 overwrites the data parameter), #1210 (Creating script and link tags now work), and #1463 (jQuery.global has been re-too
led to no longer leak memory and slow things down).
