[Problem]
In bugzilla 3.0.3, when you using IE11 to search bugs, it will pop-up message as follow:
WARNING: YOUR BROWSER DOESN'T SUPPORT THIS SERVER-PUSH TECHNOLOGY. --------- =_aaaaaaaaaa0 Content-Type: text/html
...................
In Bugzilla 4.4, when you using IE 11 to search bugs, it sent the results back to IE11, which offered to save it to a file named buglist.cgi

[Root Cause]
Bugzilla use HTML 4.01 Transitional, not HTML 5, and so doesn't support Server-Sent Events which is part of HTML5. And IE11 gets multipart/x-mixed-replace since it not follow older versions of IE.
[Solution]
Since IE 11 's string contains 'like Gecko', so add "Tridents" to detect IE.
Modified file buglist.cgi
