Subject: [PATCH] MDL-33640 - Add ability to use custom filepicker templates

Allow repository plugins to register a template by defining a get_template() method, coupled with the ability to request the template be used by create_upload_form() instead of the standard 'uploadform' template.  The template is automatically registered using the plugin's name, and core templates will override any which clash; this also means that a theme can override these templates in a custom renderer if it wants to.
