BrowserDetection: Detect the user browser and its capabilities

This class can be used to detect the browser that the current user is using to access the site.

It analyzes the user agent string sent by the browser and parses it to determine: the type of browser, the user operating system, the version, release and build.

The class may also compare the browser version against a range of accepted versions, as well if the browser is expected to support page element opacity attribute and transparent PNG images.

You can also use it for bot protection :)
