~/.gitconfig: Show tags/refs by default

This is basically `--decorate`, just a bit more how I like it.

.gitconfig

	praise = blame
	recent-tags = ! sh -c 'git tag --sort=-authordate | head -n5'
[format]
	pretty = %C(magenta)%h%Creset %Cgreen[%cr]%Creset (%an) %s
	pretty = %C(auto)%h %Cgreen[%cr]%Creset %C(auto)(%an) %s%d
[color]
	ui = auto
# Some shortcuts
