Subject: [PATCH] gtksourceview: Provide a better default style

Tango has two issues when the GTK theme is dark:

- Starting with Mint 22, its line numbers column is hardcoded to grey
and looks way too bright.
- Comments are unreadable on a dark bg.

Fixes https://github.com/linuxmint/mint22-beta/issues/60
Helps with https://github.com/linuxmint/mint22-beta/issues/5
