Version 1.6
Changes:
- Rename builder-dark.vim to builder-dark-warm.vim
- Introduce builder-dark-cold.vim variant
There are now two variants of builder-dark: builder-dark-warm (original builder-dark) and builder-dark-cold (new). builder-dark-cold was introduced to match the colder background color found in newer versions of GNOME.
(Re-tagged 1.6 release after some cleanup commits. No functional changes were made.)
