whichhead fix

The helptext incorrectly claimed that --number=N was supported.
Formatting fixes; Help message fixes
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.
Initial commit of cleaned-up dev branch
