v0.2.1a1

Emergency fix: bak config broke everything on old installs. everything.

0.2.0 release notes follow:

---

New features:

• bak list:
  • Fully colorize output (without -C/--nocolors flag, or disable in config)
  • Provide -d/--diff flag to identify .bakfiles which are identical to their original
  • Differentiate visually between entries for different original files
  • Maintain order of appearance, even when a .bakfile is updated
• bak down: add -d/--destination argument to restore .bakfiles to arbitrary paths
• bak config: modify configuration from the cli, because bak.cfg could be more intuitive
• bak get-bak renamed to bak where

Fixed: bak down can now restore privileged files by falling back on sudo cp when necessary
