[WG: Sakai QA] sakai-2.8.0 update (IE9 issues)

[Matthew Jones]

I'm also +1.

Noah, Alan and myself have tested this on a server while the network
was up (local power outage). It's easy to disable or change it to
emulate any other version of IE in the future so it will always be
useful. I avoided complicating this patch, by allowing only this
specific header to be defined rather than any arbitrary header. Only
Internet Explorer will do anything with this specific header value,
though other browsers are able to implement this (X-UA-Compatible) as
well. It's really the most convenient fix for the moment.

This was also basically the same patch used for 2.5.x, because that
release was eventually incompatible with IE8. However this is settable
via property, and the breakage under IE9 is worse this time around.
I'm also guessing that future versions of Sakai will be incompatible
with future versions of IE, so this will be good to just get in.

At Michigan the IE9 usage is pretty low, but I'm expecting this to
pick up over the summer at the labs and students upgrade.
