/*
basic function, has two tests currently, 'browser', returns shorthand for browser name,
or 'number', which returns browser number, or in mozilla's case, the rv number. You can
also use the 'full' parameter to get back both results at once, in an array.
if you need more precise browser information, get our full featured browser detection script:

Changes:
1.1.9 - added webkit detection for new range of webkit browsers
1.1.8 - fixed small error in sample code at end, msie should be ie
1.1.7 - Added default 'other' return item that will cover search spiders and other useragents
