Simplify license text, as mentioned on the mailing list.
Reasoning: it was never my intent to require anybody to copy license
text into another project if they cut and pasted something out of
toybox. The "permission for any purpose" is as close to public domain
as you can get in our current screwed up legal system without making
people uncomfortable the _other_ way. (Besides, my initial reading of
that was "all copies of the source code" but that's not what it says,
and somebody pointed out that Android has "show license text" options
because paranoid lawyers think that sort of thing applies to the BINARY
version, which is nuts.)
