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.
