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.
