feat(filebrowser): quality-of-life improvements (#123)

New features: uploading, downloading, hidden file toggle, refresh button, syntax highlighting toggle, sticky sidebar.

Bug fixes: Files are no longer renamed null when canceled, warn when files will be overwritten when renaming, confirmation when deleting files, horizontal scroll bar doesn't cover file contents when editing, copying actually increases number.
