PhpBB3 MOD: Replacement mobile browser detection for mobile themes

==Overview==
When we setup the [http://startrekguide.com/community/viewtopic.php?f=39&t=5386 phpBB3 mobile site] we wanted to exclude iPad because the normal theme looks ok on the big screen. We noticed that the browser detection script is non-commercial licensed junk. They want $50/year for 10 lines of highly resource intensive preg_match statements. Come on! That is totally incomparable with the GPL license in the install.xml file too...

Here's a new [http://code.google.com/p/dangerous-prototypes-open-hardware/source/browse/#svn%2Ftrunk%2FPhpBB3_MODs%2FphpBBmobile public domain replacement] that we wrote in 10 minutes, hope it will help any other commercial boards trying to use this MOD. It is much more efficient, and totally free. It is almost a drop-in replacement, but it lacks device reporting (you won't get the 'from my android phone' and image) and isn't 100% for old devices.

We think it is *way* more efficient in two ways:
1. We don't use pregmatch for simple matches ($50/year for this - really man?)
2. We get the common easy mobiles first, THEN we try to kick out any known desktops before doing more intensive mobile searching.

It will probably take some tweaking to get it right. If you test it and it isn't working for your mobile device please let us know.
==Install==
Upload the replacement [http://code.google.com/p/dangerous-prototypes-open-hardware/source/browse/#svn%2Ftrunk%2FPhpBB3_MODs%2FphpBBmobile mobile_device_detect.php] to /includes/mods/
==Notes==
1. It gives iPad desktop theme. Delete the first check at the top to stop that.
2. It is the same function name and true/false as the original, it will work as a drop-in replacement.
3. However, it does not return the phone ID, so the 'posted from my ___ phone' won't show a phone type. I removed this entirely to protect our user's privacy by removing the mod to posting.php (this also reduces load).
4. It is not nearly as complete as the old detect for old and strange mobile devices. It will hopefully get most new and modern devices though. It would be great to allow the user the option to switch themes easily...
5. Tested on Firefox Windows, Android (2.3.4/Nexus S), iPad, iPod.
