config.fish

1. there are two gitsh in config.fish, delete the second one
2. abbr gitpl 'git pull -v'
3. abbr gitpu 'git push -v'
4. delete z.fish and zz.fish
5. clean config.fish
6. remove stow in ~/.local/bin, it depends on other libs, and find a binary/script replacement
7. replace grep -w with extra space, since -w doesn't parse `-` like t-xa
