Add some user agent to wp_is_mobile

[inpixelitrust]

Hello,

I've run some test with the help of the twitter/G+ community on wp_is_mobile and found some mobile browser that don't pass the test.

You can see the test here : ​http://www.inpixelitrust.fr/blog/wp_is_mobile/

I was able to get the user agent of 3 of those which don't work :

HTC sensation z710 4.0.3 native browser (UA: Mozilla/5.0 (X11;Linux x86_64; HTC/Sensation/3.32.162.11; fr-de)
AplliWebkit/534.24(KHTML,like Gecko) Chrome/11.0.696.32 Safari/534.34 )

BlackBerry Playbook (Ua Mozilla/5.0 (PlayBook; U; RIM Tablet OS 2.0.1; en-US) AplleWebkit/535.8+ (KHTML, like Gecko) Version/7.2.0.1 Safari/535.8+ )

Could be great to add those to the UA sniffing :)

regex based on detectmobilebrowsers.com

Now use the detectmobilebrowsers.com regex that is more powerful but is not updated from 2014 but surely is better that the actual solution.

The patch looks reasonable, but a bit more complex.

In general I wouldn't recommend doing UA sniffing. Should we really further encourage a bad practice? Core uses wp_is_mobile() only in a few places, mostly for historical reasons where touch devices were not considered before.

There are many themes that use this function and also plugin.
I know that the patch contain a complex regex but recognize the majority of mobile os.
Maybe we can choose to use a different regex more light.

I'm going to wontfix this based on #33704 (removing reliance on wp_is_mobile()) and [40907] (introduce a filter on the return value of the function).
