append() evaluates script tags with non-script types

Using $(document).append(content) will strip out all script tags from

content and attempt to evaluate them. This throws errors when the

script tag contains content other than JavaScript, even when the type

attribute of the script tag is set appropriately. Normal browser

behavior is to ignore such content and not try to evaluate it, but

append() is inconsistent with this.

I added an exception for my specific case (text/html content for use

with John's micro-templating[1]) so the script tag would not be

stripped and I found no issues when appending (IE6/7/8b2 on IETester,

Chrome, FF3/2 linux, Opera 9.51 linux.)

It would be useful for append() to follow the behavior of browsers

regarding script tags and only attempt to evaluate scripts when the

type is missing or is a recognized script mime type (text/javascript

or application/javascript.)
