Massive changes:
* Custom post type is removed. Didn't make much sense to force users to create a custom post type just to use the plugin.
* Users can choose which post type they want to use the plugin with. It'll work with any custom post types they registered via another plugin or manually
* Users can add a filename prefix to their images. Working to make the name the name of the attachment as well
* Implemented the option to input a new upload folder within the blog's upload directory. Unsure if this feature will be kept. Will provide option to follow wordpress's method of media sorting

Release to be expected after or on the next push.
