[Feature Request] Follow XDG Base Directory Specification on Linux

[sukanka]

background

Currently, yank-note put all user files in ~/yank-note, but it would be better to follow the XDG specification, see XDG Base Directory Specification.

There are few files in ~/yank-note, and they can be easily classified.

➜  yank-note ls     
config.json  extensions  histories  pandoc-reference.docx  plugins  themes

config.json should go to $XDG_CONFIG_HOME/yank-note (defaults to $HOME/.config/yank-note when the environment variable $XDG_CONFIG_HOME is undefined.)

And extensions pandoc-reference.docx plugins themes should go to $XDG_DATA_HOME/yank-note, which defaults to $HOME/.local/share/yank-note,

Finally, histories should go to $XDG_CACHE_HOME/yank-note, which defaults to $HOME/.cache/yank-note.

suggested solution

Only the following lines need to be changed. You can follow https://github.com/rivy/js.xdg-portable,
