returning path when using 'info' command + provided GET query parameters

[nicolasmure]

This PR adds a 'path' key containg file's path + name to returned array when using 'info' command.
It also allows to set GET query parameters (previously guessed from $_GET), to enable sub requests.

Related to # 128 on the bundle side.

Well, it looks fine, but as for me, breaking public method signature will require to mark elfinder api as new major version of the library.
P S. Currently i rewrote some parts of the library (removing direct access to global arrays, replacing by Symfony HttpFoundation component), and covering with unit tests, hope will finish first part till the end of the week.

Thanks for your consideration,

I understand the need to make a major version tag, if it's OK for you, you can go ahead.
Or you may want to integrate some of these changes into your rewrite?
