Add BlackBerry 10 User Agent String #3333

As the new BB10 OS keeps on comming, RIM released the new BB10 User Agent String:

Mozilla/5.0 (BB10; <Device Model>) AppleWebKit/<WebKit Version> (KHTML, like Gecko) Version/<BB Version #> Mobile Safari/<WebKit Version>

Explanation:

• 1.Mozilla/5.0 Mostly customary, historically used to indicate Mozilla compatible browser
• 2.BB10 The primary identifier of a BlackBerry 10 device
• 3.<Device Model> Device product name
• 4.AppleWebKit/<WebKit Version> The WebKit Version number
• 5.KHTML, like Gecko The engine WebKit originated from
• 6.Version/<BB Version #> The software version number
• 7.Mobile Indicates the device is mobile; it may have a small physical screen and potentially limited bandwidth
• 8.Safari/<WebKit Version> Mostly customary, historically used to indicate Safari-compatible browser
