Include new bat themes introduced in v0.13.0

[stefanfrede]

Hi!

bat introduced with v0.13.0 new themes, in particular Nord, which I'm using more or less everywhere.

It would be amazing if the new themes could be integrated into delta, because I use base16 at the moment which is a tat bit too dark and makes diffs hard to read.

Thanks.

Hi @stefanfrede sorry for being so slow, I lost some notifications. Yes, absolutely, I've just added the new themes in master (not released yet).

Incidentally, delta reads bat's custom themes/syntax dir. So without having to compile delta or wait for a release, we can add a new theme by copying the foo.tmTheme file to ~/.config/bat/themes/ and calling bat cache --build. So to add e.g. Nord, one can do

cp /PATH/TO/bat/assets/themes/Nord-sublime/Nord.tmTheme ~/.config/bat/themes/
bat cache --build
