/* this class is used to detect os, browser and browser version.
Get the information like this:
bp.platform -> OS
bp.browser -> Browser
bp.version -> Browser version
if the detection fails, the return will be some standard values (fallback - std, std, '')
You can set Your own strings for the detection, so You may use less then 21 stylesheets ;-)
