We're in the middle of renaming 'fetch' to something else as there are
already other programs using the name and we don't appear in any searches.

• Fetch now supports bash 3.0+.
• More cleanup
• The text is now by default colored according to your distro's logo.
• Removed $*_color variables/flags in favour of a general $colors
  variable/flag. See my writeup here: #96

  is now calculated by fetch automatically.
• Image sizing now takes terminal height into account.

fetch --size 70%
