Shodo

Added code params

Improved error message of removing words.

* Shodo respects `XDG_CONFIG_PATH` now.

**Note:**

The old credentials file `~/.shodo/credentials` won't be used from this version.
So, please remove this file manually if you had used older versions.

* Improved lint messages to be sorted by line numbers.

* Added `shodo login` command.
