PlUploader Developement

Partially Implemented new uploading scheme for *MediaFile* view

Notes:
* **Media File** tab no longer has *server* and *path*, but a single field for both the server and the path
* **Upload** tab now has the plupload widget, and the user can select where to upload said files. User can only upload to local destinations (i.e. can't upload to s3, or other ftp server).
