commit 0ad3d4eddfb0c260791dc3a6383f3a1047c972ab
parent efad574780975ee22f2826900ac2a62883b02c40
Author: Kornelije Sajler <xajler@gmail.com>
Date:   Wed, 25 Apr 2018 22:15:11 +0200

Updated st 0.8.1. Used new patches, scrollblock and alpha fixed.
Created run-patches.sh, runs all patches on clean st 0.8.1 code.
All old patches remvoed, including trasparency diff.
Not including solarized theme, don't see value of it.
Commented colornames array with color indexs from 0-15, includes index 255, and afterwards bg, fg and cursor, change those for background, foreground and cursor color. Seems better than solarized toggle.
Updated README.
