Userstory

As a enterprise user, using bleeding edge unreleased IE version, I want to use JIRA deployed into our intranet, without seeing red error message saying Internet Explorer 7.0 is not a supported browser.

To Reproduce

1. way 1
   1. install JIRA to intranet domain address
   2. configure IE 11 to use compatibility mode for intranet sites
2. way 2
   1. add your JIRA domain to compatibility mode sites list
3. access JIRA
4. now you should see red bar at the top of the page

The Cause

This issue is cause by the fact, that when coding JIRA you had no idea what kind of user-agent string Microsoft would use for IE 11 and hence have no support for recognizing IE 11, when it's in compatibility mode.

The Fix

I have added a .patch file with simple fix to detect if browser, that reports itself to be MSIE 7.0, is in fact IE 11.
Note, you might want to future proof yourself by detecting that Trident version is greater than 6.0 or 7.0 and decide, that this is in fact also IE that is newer than IE 11 and doesn't need warning about IE 7.0 not being supported.
