* Added new dependency: rimraf. This will be used by chunked upload support to bulk delete temporary chunk files.
* Added chunked uploads support :3
* Updated Dropzone to 5.2.0.
* More improvements to thumbnail view. Delete button will now only appear on hover. Some other details, such as file name, size and album/owner will also appear on hover. Touch devices will have all of those appear always visible by default.
* Image thumbnails will now appear on home page after successful uploads (only for WEBP, JPG, JPEG, BMP, GIF and PNG files). WEBP may not work properly in Firefox though.
* Refactored home.js to use const/let and some other stuff.
* Refactored album view. It will now display properly on mobile screen. Download Album button will also no longer be located at the top right, but right below the subtitle.
* Updated some version strings.
* And maybe some others that I can't remember.
* Added "Size" column to list view of uploaded files. The size will be use 'pretty' view (kB, MB, etc).
* Added delete button to thumbs view of uploaded files.
* All instances of "file length" in public views renamed to "file name length". The latter makes more sense.
