Implemented access to the relative path property for uploading folders (

#131)

* Implemented access to the relative path property for uploading folders

Added the ability to access webkitRelativePath from the IFileInfo interface, allowing for the support of structured folders to be uploaded using <input>.

* Changed the webkitRelativePath property to a Dictionary of nonstandard File properties

* Remove unused class
