Adjust dojo.isIE when EmulateIE7 header is in use

[James Burke]

As opposed to the user clicking the compatibility button in IE8, if the web site uses the EmulateIE7 header/META tag, then we should adjust the isIE to match. Something like:

if(dojo.isIE >= 8 && document.documentMode == 7){
   dojo.isIE = 7;
}

Bill said Cougar needs to know real IE version for some emulation quirks in rich text editing. In the above case, define a isRealIE property with the originally detected version of IE.

FYI when you actually press the IE7-emulate button in IE then dojo.isIE is set to 7 (as one would expect).... and I think that was the case that Cougar was actually talking about.

But in short, in both cases, dojo.isIE should state the emulated version, and dojo.isRealIE (or a less confusing name like dojo.realIE, we should probably get rid of all the "is" words in 2.0) should state the real version.

Bill, OK in that case I am not sure we have something we can test that will tell us we are in emulation mode: when that compat button is pressed, then IE changes the user agent too.

If Cougar has a reproducible case, he can pass to me, and I'll see if I can get it to Microsoft for their evaluation.

The more I think about it, I do not think we should provide a "realIE" flag. IE not changing the navigator.userAgent with x-ua-compatible is used may be a bug (it does for the compat button). I'll see if I can ask Microsoft about that.

So for now, I'll just set isIE to the documentMode unless documentMode is 5, quirks mode, and leave out an realIE value.
