Detect ClickOnce support of browser
Detect if ClickOnce is (or rather: might be) supported by the browser.
This is partly based on https://gist.github.com/adunkman/2371101.
If the userAgent string does not contain a .NET feature hint,
we settle for everything that looks like an IE, because .NET
is installed nearly everywhere nowadays.
It might also be a good idea to check for the X-ClickOnceSupport
header on the server side.
