Quick fix to error text

Fix mktar

SHA1 checksum files were created regardless of existence of corresponding
file. Worse yet, they weren't actual checksums.

Fix unittest

Help text specified wrong option.

Formatting fixes; Help message fixes

Added core README; dropped one not-so-useful script

Refactored code into multiple 'packages'. One day these may be
independently installable. For now it's just an organization method.

Rewrote main README and added per-package READMEs.

Also: bug fix on whiched and whichvi. They formerly propogated an error
if $EDITOR or $VISUAL were set to a non-existant executable. Also
improved the inline documentation.
