Added Namespace+Autoloading compatibility

[WietseWind]

Little piece of PHP to make Mobile_Detect auto-loadable in PSR-0 compatible PHP autoloaders like the Symfony Universal ClassLoader by Fabien Potencier. Since PSR-0 handles an underscore in classnames (on the filesystem) as a slash, "Mobile_Detect.php" autoloaders will try to convert the classname and path to "Mobile\Detect.php". This script will ensure autoloading with:

• Namespace: Detection
• Classname: MobileDetect
• Namespased: \Detection\MobileDetect
• Autoload path: ./namespaced
• Converted path: ./namespaced/Detection/MobileDetect.php

@WietseWind thanks for pointing it out. This was mentioned before in #80
My only concern is that many people using the class are still using PHP version < 5.3.

Not sure how to make the transition yet.

@serbanghita The great thing about my suggested fix is it's on top of de current, unnamespaced, un-autoloadable class; it just namespaces and extends the current class. Without any changes people can choose to use the (unchanged) unnamespaced version, or the namespaced, autoloadable one.

@WietseWind I planned to respond earlier but god distracted. So, I got it now, I was missing the context. Is there anyway you can provide a real world example. I'm interested in explaining the new folder to people. How this changes the integration of the script into Symfony. Thanks!

Hi @serbanghita,

The Symfony Classloader makes auto-loading classes very easy;

1. Include the autoloader, and define the classes + source-location (stored and coded in the PSR-0 standard)
   
2. To use the class, you just need to "use" the namespace+class. Now you can just create a new Class, no more inluding required. When the class isn't used, it isn't (auto) loaded so no memory-overhad.

You may want to use slashes instead of DIRECTORY_SEPARATOR, they work in windows too.

[serbanghita]

@vlakoff I don't see no reason to replace DIRECTORY_SEPARATOR (on nix is / on win is \).

I just think it is a true pain to read :-p (which leads to worse maintainability)

This article has made a perfect summary. That being said, we don't want to go off-topic ;-)

Good change! I started using your code inside Symfony2, and it's working!

Greetings!

[WietseWind]

@DaniSancas Great :)

[serbanghita]

I'll tag this in the 2.6.4 release. Thanks a lot!

[WietseWind]

Great, thanks!

Another small thing, since PHP 5.3 is required, you are sure the __DIR__ constant is available ;-)
