Title:  Show warnings if JS is disabled or when the detected browser version is outdated

* The Echo3 server-side implementation now adds a noscript-element
with a warning that shows up when JavaScript is disabled in the user's browser.
The text and link displayed can be customized in ServerConfiguration.

* A warning is shown at client startup when the detected browser version is considered outdated
by the current Echo3 client-side implementation (detected in Echo.Client._isBrowserOutdated).
The text of the default warning implementation Echo.Client.DefaultOutdatedBrowserWarning
can be configured using new 'ClientConfiguration' properties or substituted
by a new implementation analogous to WaitIndicator. An example implementation is included in
the interactive test application. The warning can be disabled by setting the
ClientConfiguration.OUTDATED_BROWSER_NO_WARNING flag.
