memo-cli will now look for an existing db file in the parent folder until it's found or until we hit root.
currently will panic if the program lacks permissions to do so
windows support is still a loooong way to go
- replaced env!("HOME") with dirs::home_dir()
- replaced libnotify with notify_rust
- set to use bundled libcipher (encryption not implemented yet)
there's still much to do: server discards symbols in filename but base64
might produce symbols. The edit sync is broken: new memos will be
synched but not edited memos. Also it's pretty janky but I have to start
somewhere.
