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.
