Warning for unsupported browsers

Description

Make the webapp able to intercept the unsupported browser type (eg. IE 11) before loading MS to redirect the user to a static page that contains a warning message, something similar to the following:

My proposal is to add this lib that allows us to quickly filter browsers among a non configurable list , which is Chrome, Firefox, Safari, Edge.

Detection will be made at the very top of the application and specifically in the StandardApp component here
if the browser family is not among the 4 mentioned above then a redirect to a specific informative page will be performed

Also the examples will be updated with new redirect functionality or with some mask

Another possibility is to detect browser familiy before running everything at index.html level

@MV88 @offtherailz if we can do that without adding a new library is better in my opinion. @offtherailz let me know your thoughts.
