Fix traffic monitor in mobile MSIE11

Mobile Internet Explorer 11 (on Windows Phone 8.1) does not have flash and forcing to IE7 mode causes the traffic monitor to not display. This did work in the past.

Using the developer tools in desktop IE11, I noticed that IE7 mode and IE10 mode show the traffic monitor graph. IE11 mode it doesn't display the graph due to not being detected as IE.

My change basically sets the mode to IE7 or IE10 for pages using svgweb.
I have also set the mode to Edge for some other pages, which is already the case for almost every single .asp fie.
